MTN South Africa

I had renewed my contract with MTN last year 9 June 2020. The same day I realized the cellphone I wanted was not what my son required and I cancelled the deal with MTN same day. I received confirmation that the deal was cancelled by e-mail from retentions department. I received no cellphone but my contract shows that it has been renewed. I tried everything since 2020 to get MTN to cancel the contract since I received no cellphone and I have e-mail proof from retentions that the deal was cancelled. I have been a client of MTN for more than 15 years but my attempt every month to resolve this issue was in vein. I was referred from post to pillar every month as they can see it on the system but cannot refund me the extra funds until retentions departments has confirmed my story. To date I cannot cancel nor renew my contract on that number because of that transaction for which I am billed but had received no cellphone. I am a frustrated customer as no one is willing to help me. MTN consultants refer me monthly to their retentions department which the number is always busy until my airtime gets finished. I am financially drained from calling and loading airtime just to hold for hours. I really need help to get my issue sorted out. No delivery of the cellphone was done, please refund me my funds and cancel that contract on my number.
