Dispute

Good Day I had a ********** contract with Vodacom that Ive been trying to resolved since 8 months ago and I got a response from Vodacom confirming that its a ********** contract. So I got a letter from Vodacom confirming and all I had to do was send it to Transunion for them to fix my report and i send an Email to Transunion and got a reference number(TU ********** 7-000137-01) to fax together with the documents but I still got no response and my credit scored was affected severely. Please help.
