JPMorgan Chase Debt Collection Complaint

JPMorgan Chase Debt collection department,

Non-federal student loan Cont'd attempts collect debt not owed Debt was paid North Carolina

I paid of my JP Morgan Chase student loan more than - years ago and even received an email congratulating me for paying off my loan. Recently, I began receiving emails from Chase about my balance being available, but when I logged in to their website, there was no balance. I assumed this was a computer error. However, Chase apparently has sold my imaginary debt to -, which now claims my debt is $93.00 plus $18.00 in unpaid interest. There is no way this is even possible. - days ago, I submitted a written request for verification of the debt to -, at which point they began harassing me with phone calls multiple times a day. Then today I received an email from - saying my request could not be completed because I never returned their calls. I realize this is for a small amount of money, but it is money that I do not owe, and I have a right to receive written verification of the debt. My credit has already been ruined by student loans and I 'm not going to start paying made-up debts that I do n't owe.
