Never take out contract with MTN

Please never take out a contract with MTN. I write this review for my father-in-law JF Lezar as he is close to a heart attack about MTN’s behaviour. It seems impossible to cancel a contract with MTN and it seems that MTN is doing everything in their power to harass their customers. The contract of JF Lezar expired on 03 October 2020. According to contract the contract was cancelled on 23 August (ref no ***). MTN confirmed cancellation by increasing the debit order amount for remaining two months. However, after two more written requests JF Lezar received an sms on *** on 5 January 2021 stating that the amount if R604.21 has to be settled to complete migration (email also received - ref ***). Although no money was owned to MTN, this amount with ref BA***1 was still paid and proof of payment confirmation was sent to customer care (ref ***). Today Koos received an sms stating that his contract will be cancelled in December 2121. How can MTN simply ignore my cancellation requests ans simply extend the contract until December? Nobody gave any consent to that or signed anything. Dear MTN please cancel my contract immediately and migrate my number. Nobody at MTN knows what the other person is saying. Do you have a database? If yes, please have the decency to train your people.
