Trashy Telkom

Since I have contracts with Telkom mobile I have never experienced any problems, however now the end of January when the debit was supposed to go off my account on the 23rd they did not debit, after waiting a week as the usual debit is the 25th of every month still till I had funds the debit still did not go off. Now today Telkom mobile cuts my lines. Where as they could have double debited the account in question on the 25th of February as the mistake is on their side....
