TELKOM'S BAD SERVICE ON DEBIT ORDER SYSTEM

My account is up to date.. On the 1st of October Telkom decides not to debit my account. 2 weeks later they decide to debit 2 installments. When I call their so called contact centre the lady replies by saying 'I don't know'. Now they decided to hand over my account to collections as I did not have enough in my funds for 2 installments but only 1 installment that they conveniently decided not to debit. Such level of unprofessionalism is totally embarrassing. I regret ever taking out any contract with Telkom. Never again.
