I received a letter from National Credit Services indicating they collecting on an old debt from a former apartment complex. I sent in writing a letter disputing the debt and the amount owed. The next communication I received from them was a letter stating I failed to setup and arrangement or respond and they were getting ready to report to the credit bureau ( dated XXXX XXXX ). After receiving the letter on XXXX XXXX I called to inquire about my dispute. The agent was very rude stating they verified with the apartment complex and it was valid. He told me a letter was sent XXXX XXXX. I told him I only received the XXXX XXXX letter with no mention of a dispute, letter, or bill. He stated they did n't have to send it and continued to try to collect the debt. I requested a supervisor who also stated they sent it, I was on a recorded line and they had me on tape saying I received it. I again stated I had not received a statement or acknowledgement of the dispute and I believed they could not report until they acknowledged my dispute and validated the debt. He told me they would report me over the weekend of XXXX XXXX if I did not make a payment, he offered to set up a payment plan then stated he would send me bill from the creditor after I did so. I setup a payment to receive a copy of the bill and save my credit score. I do not believe this company followed the law because they did not send me verification of the debt, prior to continuing collection efforts. To date I have n't still have n't received a copy of the bill which they allege they initially sent on XXXX XXXX.
