I received a letter from IC System back in XXXX XXXX, 2015 stating that I have a balance due from XXXX XXXX XXXX. I was shocked and researched the issue with XXXX XXXX XXXX immediately. XXXX XXXX XXXX confirmed with me on the phone and in writing that I did not owe them any balance and the communication from IC System is incorrect. Then, I contacted IC System to explain the situation to them on XXXX XXXX, 2015 and the representative ( XXXX ) advised me to mail them a dispute letter. Then, I did mail IC System two dispute letters. After I sent the dispute letter, I follow-up with IC System three times on the phone on XXXX XXXX, XXXX XXXX and XXXX XXXX, 2015. IC System advised me that the status is pending the response from XXXX XXXX, but they will not report my file to the credit bureaus as they still need to do a investigation. However, I just realized they reported my file to the credit bureaus few days ago without clarified my account with XXXX XXXX XXXX. I called IC System today, XXXX XXXX, 2015 and seeking for help. Their response to me is I am sorry they can not do anything about it, I can dispute that from the credit bureaus if I want to. I believe the whole process make me very frustrated and helpless because of the mistake of a billing.
