Lp investments is the THIRD collector coming to collect a debt that has been paid already. I am seeing the way this works now, one company sells their portfolio to another, meanwhile the new company who purchased it tries to make money off of paid debts as much as they can. If you don't have your proof of payment they will threaten you so that you will send them money for debt's that have already been paid. Notice all these companies don't have websites either! That's because they don't want to be accessible . Also the company who was collecting the PAID debt is called First National Collection Bureau, Inc. They don't even have the phone number to the people they work for what a coincidence!
