Telkom unprofessional services

My account was debited twice in the same month. I phoned to follow up and was told that the account was no longer in arrears. I called to follow up the refund and was told they waiting for credit to update the payment. Everytime I phone to follow up it was a different story on the other line. No clear communication. I want my refund back as my account should have never been double debited. As a long standing client of theirs I'm very disappointed.
