This collection agency has had 135 complaints against it with the State of Colorado Attorney Generals office.

They have been admonished 5 or 6 times for illegal collection activity.

They are in my opinion a very unethical business if you have had problems with them and feel they have violated your right contact the State of Colorado Collection Agency Board at (303) 866-5304.

I believe this collection agency uses poor business ethics .

If you have had collection issues with this agency and feel they violated your rights

First Notice

Within 5 days after you are first contacted, the collection agency must send you a written notice stating the amount of money due and the name of the creditor who referred the debt to the collection agency.
Your Rights

You may dispute the debt (or any part of it) within 30 days after receiving the first notice. Your dispute must be in writing. The collection agency must then stop collection efforts until it mails you proof of the debt (a bill or court judgment) and the name of the original creditor if requested (if different from the creditor listed on the collection notice).
You may inform the collection agency to stop calling you at work or at home, limit the hours during which they call, or to contact you only in writing only. Your request must be in writing. The collection agency must comply with your request but may sue you if it believes the debt is valid. If you are sued, you have the right to appear and defend yourself in court.
You may refuse to pay the debt or inform the collection agency to cease communication. Your request must be in writing. The collection agency may send you one final notice of its intentions. It must then comply with your request but may sue you if it believes the debt is valid. If you are sued, you have the right to appear and defend yourself in court.
You may ask the collection agency for a copy of your payment history. The request must be in writing. You are entitled to one copy a year free of charge. The collection agency may charge up to $5 for additional copies.

Communication

A debt collector may not:

Contact you by postcard.
Use an envelope that shows that the sender is a collection agency or that the contents concern a debt.
Call you before 8 a.m. or after 9 p.m. your time or at any other time or place which the debt collector knows is inconvenient for you. (If 8 a.m. to 9 p.m. is inconvenient, notify the collection agency in writing and state when you can be called).
Discuss the debt with those who do not owe it without your consent or a court order. The debt collector cannot state he is a debt collector or affiliated with a collection agency unless specifically asked. (A spouse or co-signor is generally responsible for the debt and may be contacted). Neighbors and relatives may only be contacted to obtain your address and phone number.

Contact you if you are represented by an attorney. (You should provide the attorney’s name and telephone number to the collection agency).

Prohibited Collection Practices

A debt collector may not:

Use obscene or profane language.
Make repeated telephone calls to annoy or harass, such as calling and speaking to you three times in one day.
Telephone you without stating his name within 60 seconds. The debt collector may use an alias (false name) if it is listed with the Colorado Collection Agency Board.
Threaten violence against you, your property, or reputation.
Publish or post the debt through any list other than a credit bureau report.
State that he is an attorney if he is not licensed to practice law.
Claim he works for a government agency or has governmental authority, if he does not.
Accuse you of committing a crime or threaten you with arrest.
Misrepresent that papers are legal documents when they are not or that papers are not legal documents when in fact they are.
Misrepresent the amount of the debt or collect an amount greater than the amount you legally owe.
Threaten to take actions that are illegal.
Threaten to take or sell your property, garnish your wages, or attach your bank accounts unless that action is legal and the debt collector intends to do it.
Report false credit information about you.
Make you accept collect calls or pay for telegrams.
Deposit a post-dated check before the date on the check. If the check is post-dated by more than five days, the debt collector must inform you in writing no less than three days nor more than 10 days before the date the check will be deposited. (A debt collector may ask you to write a post-dated check - the choice is yours).

Actions which are not prohibited

The CFDCPA does not prevent a debt collector from:

Contacting you by telephone, letter, telegram or in person (unless you have requested in writing that the collection agency not contact you or you are represented by an attorney).
Refusing partial payment or suing you unless you have a payment agreement with the collection agency and are complying with it.
Adding interest to the debt if permitted by law or contract.
Adding information about the debt to your credit report. However, if you dispute the debt, it must be reported as disputed.
Adding the following charges for a “bounced check” (check not paid by your bank upon presentment due to insufficient funds or a closed account): (1) a return check charge up to $20 if posted at the creditor’s business or in your contract; and (2) collection costs of $20 or 20 percent of the check amount - whichever is greater; and (3) the amount of the check. If you receive a notice to pay an NSF check and do not pay all charges within 15 days from the date the notice was mailed or served, the collection agency can generally sue you for 3 times the amount of the check for a minimum of $100 plus court costs and reasonable attorney fees. For example, if you write a check for $4.50 and it bounces, you may owe $44.50. If you do not respond to the 15 day notice, the collection agency might sue you and get a court judgment for $300 ($100 for the check amount, $150 for attorney fees, and $50 for court costs).
