MTN Fleurdal Mall branch - HORRIBLE branch

I wen to the MTN Fleurdal mall branch to cancel a contract on one of the numbers on my profile. This was on the 10th Jan 2026. The contract in question ends on 12th Feb 2026. The guy who helped me said to come back on the 12th Jan 2026 (30 days before the ending of the contract) or call 135. I tried calling 135 multiple times (3 times) and one of the calls lasted about 38 mins and did not get helped. I went back to the Fleurdal Mall branch, where I had opened the contract, on the 12th Jan 2026 and a lady told me that there is nothing they can do, in fact they do not cancel contracts at any branch. She added that even if I was to go to the headquarters and request a contract cancelation, they would not help me. I am saddened that the whole ordeal amounted to nothing when I had exactly 30 days to cancel and now have to pay another installment even after the contract end date.
