Incompetence

How to begin? I have been a Telkom mobile contract customer for the last 11 years, i had absolutely no issues with them until end of last month (july 2023) let me explain. So on 26/07/2023 i got an sms stating my account payment is as follows. R1317.13 for end of july and R580.50 overdue payable immediately. So that is a total of R1897.50 correct? On 27/07/2023 my service was interrupted due to the arrears amount and i paid R581 immediately to have service restored which it was. On 29/07/2023 they took a debit order of R1897.63 of which is the R1317.13 plus the R580.50 arrears, i didn't mind as now i know i paid R581 in advance correct? Then on 04/08/2023 my service was interrupted due to non payment.. Now i was confused. So on 05/08/2023 i phoned Telkom on 081180 and asked what is going on? The consultant told me the mistake was on their collection department side and my service wil be restored within 5-24hours, great thanx. But my service never got restored. On 10/08/2023 i phoned Telkom again, explained the situation and the consultant confirmed that i paid R581 in advance and told me my service will be restored within 5 hours, also apologized for the inconvenience. Now today is 14/08/2023 and my service is still not restored. So tell me? Is this how Telkom mobile gets customers to refer others to switch to telkom? Or maybe after 11 years i should switch to another provider?
