Bad customer care

I took out a cellphone contract with Telkom mobile in May 2021. Ever since I've had the contract, it has been a complete nightmare. Firstly they debited my bank account on the wrong date and caused me unnecessary unpaid debit order fees. When I called to querying the debit and my number blocked due unpaid amount, an agent called Asive told it's not her problem that my number is locked. And further told I should sort it out with my bank. I felt disappointed and disrespected. It didn't end there. I called again and another male agent assisted and advised me to pay the errear amount and my number will be unblocked and I did that. But to my surprise it was unlocked after 3 days of paying and the debit order was deducted from my account again on the incorrect date again,however it went off and after a week, the number was blocked again. And I called for the 3rd time and was told a query was escalated and my number will be back on in about 3 hours time. And that didn't happen. And after 3 days again my number is still locked and I called again this morning and was told it's an error and the query is being escalated and my number should be back on in 5 hours. Until now 18h00 ,from 9h00 my number is still off. This has been going on for 2 months now and I have no hope or whatsoever in Telkom mobile network. And everytime I call I'm being from pillar to post and I'm tired of them. Today I spoke to an agent called Nokuthula Nkosi, who sounded very friendly but my number is still off. Can someone please sort out Telkom, their service is bad to the core.
