Pathetic and thieving

In August 2025 Mondo contact me offering me a new MTN contract

After some back and forth I agree to the new contract and the represented told me that this will supersede and my terminate my old contract. I confirmed this again when the representative told me that i would need a new SIM card. Fast forward to today I am still being billed for both the old and the new contract and MTN wants to charge me R1,000 cancellation fee on the old contract or I have to carry on paying month to month. So Mondo **** to me

Additionally I went to MTN Newmarket and waited over 90 minutes on Friday 30th January to be told that I they cant help me and I have to phone Mondo for the call recording. I went home and called Mondo the representative says there's nothing she can do to help I have to drive back to MTN and they must phone Mondo for the call recording. She cannot send it to me. I was polite and friendly and yet she put down the phone on me as soon as I asked for an investigation.

I am still being billed and MTN and Mondo make it impossible to follow up
