This agency never sent a single notice of an account in collection, which allowed substantial interest to accrue on the account. Once I found out about the collection when checking my credit report, I contacted them to ask them to provide a written notice or invoice, which never arrived. They insisted that I give them numerous phone numbers and my employers name. I did not give them a real phone number. Instead, they tracked down my parents and began to harass them, demanding that they make my pay the account immediately "or else" and if I didn't "then I'd be sorry." I have since called the agency to complain that I did not receive notice of the collection and they refused to resend the notice and threatened me with civil action. I asked to speak with a supervisor and the agent hung up. How can I pay the account if they wont even provide documentation of the collection? This company needs its license revoked.
