I was paying on a bill and missed one payment so the account was sent to an outside collection agency. I was not aware that it had been forwarded on to this company. I was never notified by the collector that they had my file in their office, they are telling me that they do not have to send me a letter or statement to notify me of their intent to collect the debt. How can I dispute something I was not aware was sent to them or know the balance owing, or where to send the payments if they do not send me any info in regards to the account?
