Telkom at fault for changing account details

Telkom created a new account number without informing me. I have been paying. My line then gets suspended. When we call in to query, they inform us that we have been paying into the wrong account. But that is account that we have always been paying into for years. They then transfer the funds with a reference number. 4 days later we call again and they still waiting for funds to be transfered from within their accounts. And I am told we have wait another 5 working days. Also we are billed for the month of March. I had requested to speak to a manger on 29 March given my cell details to call and to date 3 April I have not received a call but I have make a call and reexplain my case. Ask for a manger and waited 10 mins. I had once again explain the error that Telkom made. I received two reference numbers, one to unsuspend the line today, second to transfer funds to the new account. When I queried the billing for March the manager says she does not how that can be done as billing is automated. I requested to speak to someone in billings department she says that can not be done. This was a fault of Telkom, they can easily suspend my line but still bill me for March. We phone was not in use for 3 weeks, due to their fault but they still me.
