The first call I wastold about owing the debit. I questioned the debit and requested an invoice. The collection agency then gave me a number to call to find out more about the debt. The number was to an over seas call center who informed me they could not send me an invoice because the invoice would be marked as paid. I then call the vendor ( XXXX XXXX ) who indicated that I did not owe anything to them and they did not send it to collectiona. The vendor called debt collection and took care of the matter. A month later I received another call from this collection agency on the same debt. I indicated I did not owe this, the vendor does not think I owe them, and to stop calling me. I was then told that they would decide the matter for me. When this collection agency calls it is a robo call and even if you answer the phone they just give a recorded message to call back.
