Poor client service

I have a Telkom router contract with @TelkomZA but I am not happy with the service I have been receiving of late. In August I missed my payment for the router and was subsequently cut off the service, understandably so. September I was charged double the amount of my premium, didn’t make sense since it had been cut off but I paid nonetheless. For the duration of that month, my services were still suspended and when I queried I was told the payment was still in collections and had to be processed to my account. Kept calling to escalate the query which was finally resolved after 21 days which means I again paid for a month I had no access to service for. Now in October I didn’t make payment as I was fed up with the service, had since disconnected my router in September and now to my surprise, last night I was again debited twice, for a service that has since been unavailable since September. Please help me understand how @TelkomZA works because from where I’m standing it’s becoming a ****.
