Poor service from MTN Supersonic Fibre

I have been trying to cancel my MTN Supersonic contract since November 2021. After numerous emails to the cancellations department I only receive automated responses.

Every time I spoke to the customer service desk the person just tells me that someone will contact me. Up till now nobody has contacted me, either via email or telephone.... It is nearly the end of February 2022 and I still receive monthly bills from MTN.

I have never experienced such lack of helpfulness, I must say I will never recommend MTN Supersonic to anyone!!
