Credit Bureau Acting On an Incorrect and Unverified Information From MTN

MTN has listed me as a defaulter claiming that I opened 2 more contracts with them but failed to pay. Since I never knew about the contracts, I asked for either contract document or recording they since failed to produce them rather point me to a lady from international company who was claimed to be the one opening the contract with me. They called this person she could not be found; they wrote her an email copied me; the lady has not responded until now. Further, than that, MTN said they cannot help me. Neither MTN nor SAYA (decbtor collectors) can produce any contract as evidence claimed I have with MTN. I have called every department at MTN; collection, customer service, billing, no one was able to help me or rather track the details about my contract with MTN. Failure for MTN to account, yet they handed me over as a defaulter, inaccurate and unverified information was clearly submitted and processed by both SAYA and Credit Bureau. I am so disappointed about the Credit bureau who could not verified there's ligitimate contract and confirm the accurate information from MTN; what an unfair treatment and I received from both MTN and Credit bureau. I plead that justice be app**** in my case.
