Very bad service

I canceled my account on the 1st of August 2022 and I they are still debiting my account, when I call they always say they are going to escalate and someone is going to call me but never received any call from them. It is very hard to get those people on the phone. At some point Iwas told to hold on the line for customer care and I held for about 30mins and they still cut me off and bear in mind I was the one who called them. I decided to reverse these amounts because they are not responding even on my emails. Last week I received an email saying that I owe R360 and they are threatening me to say that I must pay within 7days. Today, 26 October 2022 I phoned three times with no luck, the third time I was told that someone is going to call me. Let me say I am happy that I am cutting ties with them, just imagine if I was in trouble and need their urgent assistance. I still need this thing to be resolved. I am not getting any joy with them.
