ACE Cash Express Claim I owe tyhem for a pay day loan. I paid it off and I have the Paid in Full Letter Nationwide

I've borrowed moeny in the past from Ace cash Express. I've paid them off and have the Paid in Full release letter's. Now they claim I still owe them . I emaile them several time's I have proof all the loan's I've gotten from them are Paid in Full. I also requested just for the sake of it, they tell me the amount I owe, date of the loan, year, and the bank the money was deposited in. They refuse to give me that info. This has been going back/forht for a couple week's now. I do have the bank statement's also showing deposit's made. I finally told them I'd see them in court if they wish to pursue this matter. It's getting old now. My last letter was from a Andrew Richardson, Sr. Investigating Officer. Law& Enforcement. His phone # is 1-813-438-6978. I have not contacted him by phone, not interested.
