<human>: Terminated contract with a previous cell phone carrier in 2008, when company was acquired.  I was within my rights to cancel due to circumstances and  per terms.  However, the purchasing cell phone company has continually reported a claim for cancellation fees to my credit report. For five years they have sold the 'debt' to multiple collections agencies and each one reports it as new without contacting me.  I have disputed these charges various times but the disputes are not permanent on credit reports. 

I also contacted the BBB in 2009 for mediation, and due to lack of supporting paperwork from the cell  phone company (they were unable to prove I was an existing customer) the BBB ended the case.

At this time, I am purchasing my first home and have been disqualified from conventional loans due solely on the dispute of this negative item on my credit report.  My credit score is strong, and I have an otherwise perfect credit report.  I was told that it is not beneficial to contact either the credit bureaus or the collections agencies now, as the dispute status causes issues with loan approval.

Can anyone offer advise on how to resolve this issue--and quickly enough to help obtaining a conventional mortgage?
