Telkom triple billing in one month

My account was paid on December 1st in full. Thereafter peoof of payment had been sent 3 times. Today I get double debited for my account already paid. Upon calling them they cannot start the refund process on my account until Wednesday next week. If I am to reverse the debit order they said they will block my account.

So they have now taken all my available funds. Refuse to repay me. I cannot reverse the debit as I will then have a suspended account.

In turn I can now not see my clients. But Telkom doesn't seem to worry about this.
