Debt collector calling me about a payment from XXXX that I do not owe. Every time I ask tell them that XXXX has never contacted me XXXX telling me I owe a dime. I have received nothing in writing from XXXX. I keep telling them that I need it in writing from XXXX before I even think about giving them one cent. This company calls me every single day with the same " This will be put on your credit score if you do not pay ''. I looked up some reviews of this company and TONS of people are having this problem. XXXX has even said they have nothing to do with them and does not use them for debt collection.
