My credit is being harmed by a collection agency that is reporting a disputed debt. 

The issue stems from a 3-month series of billing errors that my current phone/internet/XXXX provider made when we switched our service to them last year ( XXXX 2014 ). Throughout the time that the billings were in error, XXXX advised me to not make the payment while they corrected the issue however they never actually got it fixed. When they finally combined my payments onto a single bill ( which is what they were supposed to have done from the beginning ), they sent me a separate bill for one portion of the service and refused to provide a breakdown of what the billing represented. As the total amount shown was equal to the amounts I had been billed during the 3 months that the bills were in error ( and did not include the " bundle '' discounts I was supposed to get ), I advised CenturyLink that the bill was disputed until they could get it corrected - they appear to have responded by sending it to a collection agency. 

When I received their bill I notified the collection agency that the bill was disputed because the creditor refuses to provide a breakdown of charges ( which I know are wrong ). The collection agency subsequently sent me a copy of the erroneous billing, marked as a duplicate and showing an address in XXXX ( I am in XXXX ), which does not include any information other than the disputed amount. 

I contacted the collection agency and advised that the billing remains disputed because it 1 ) does not list what I am being charged for or 2 ) include the discounts that were the source of the initial dispute. Their agent stated that they considered the bill validated and were reporting it as a collection item. My credit monitoring service subsequently notified me that my score has dropped. 

I experienced a job loss several years ago and my credit suffered as a result. It has taken me a long time to rebuild and I am very upset that this collection agency is trying to erase all that hard work. 

I have submitted a complaint to the FCC as well, in the hope that they can get XXXX to correct their erroneous billing - please help me get the collection agency to stop harming me - my efforts to convince them that the billing is wrong ( and should not be paid ) have not been successful. 

Thank you,
