cancelled contract that MTN denies

<p>good day</p> <p>I cancelled a contract I had with MTN where there was a telesales marketing, upon receipt of the phones, i was not satisfied and decided to cancelled the contract. MTN consultant advised that I must return the devices within 7 working days so that the contract can be cancelled. I did as advised and returned the phones to MTN MAPONYA where I was given a paper with both phones written as returned. In March I received a call from MTN that am owing them and I informed them I cancelled the contract. they said I must send proof of which I did and sent it as an attachement to Palesa Kubeka who's signiture is retentions & Windback Agent. She acknowladged the email and copied me when she sent the email to ********** sending from email address: ********** Now MTN have handed my account to their attorneys and also listed me on transunion as a bad debt of which they never even debited my account because I cancelled the contract, they treatning me that I have 48 hours to provide proof of cancellation of which I sent in March to the said consultant above. I feel my rights as a consumer are violated and my credit record have been messed up because of MTN's fault, I don't know if they don't have record keeping in their company where they supposed to keep records of transaction.</p> <p> </p> <p>I'd like to get assistance from you</p> <p>Thank you </p>
