I was contacted by phone on XXXX/XXXX/15 by XXXX XXXX with National Credit Systems. She told me that I had a bill from XXXX XXXX that had been turned over to her office for non-payment. I explained that I had moved out of the complex and was not aware of any bill. I requested a copy of the bill be sent to me. XXXX XXXX said she would put it in the mail to me that day and put a hold on the collection account. I received a generic phone message on XXXX/XXXX/15 from XXXX XXXX asking me to call her. I returned her call and left a message. I called again on XXXX/XXXX/15 and got XXXX XXXX, she had no record of our previous conversation. XXXX XXXX said that XXXX XXXX claimed I left over {$1100.00} in damage to the apt . I explained that the apt was left in perfect condition and I had friends who helped me clean it and could confirm the condition. I again requested a copy of the bill, all the charges itemized and photographs of the so called damage. XXXX XXXX said she had a bill with a total and would mail it to me that day but could she get my credit card number and have me make a payment. I told her that I am disputing this bill. She assured me that the account was in dispute and it would not be filed on my credit. I called XXXX XXXX on XXXX/XXXX/15 because I still had not received the bill. She said she would request the bill. I stopped her and asked " What do you mean request the bill? Do n't you have a copy of it? '' XXXX XXXX said that she had requested the bill but never gotten it. XXXX XXXX immediately transferred me to a voice mail box that she claimed was her supervisor. I left a message with my account # and phone #. I was not called back. I left a message on XXXX/XXXX/15 and XXXX/XXXX/15 and have not received a call back or a copy of the bill. I did received a letter from NCS on XXXX/XXXX/15 stating that they were placing this debt on my credit history if I do n't make payment arrangements with them immediately. I filed a complaint with the XXXX on XXXX/XXXX/15. I received a call from XXXX XXXX on XXXX/XXXX/15 in response to my complaint. He said that his office mailed a copy of the bill to me on XXXX/XXXX/15 and he would request another copy be mailed. He was very abrupt and rude. He said my account is still in dispute and nothing will be filed on my credit at this time.
