Disgusted my telkom

I am extremely unhappy & disgusted by telkom mobile billing.

I have a contract with telkom of R599p/m. In january they decided not to debit while there was money in my bank account more than enough for R599 to go through yet they say it bounce, made effort calling their cust service after my bank notified me & i jave been charged a fee of R100 by the bank which also went off from the more than enough bank balance with effort i called telkom was told payment went through again i received sms from telkom i called and one lady told me it did not go through i must go pay manually and when i got to the branch to pay manually was told no account up to date payment went through i also took a picture of the screen showed to me with payment reflecting and balance due of R0 also got a call back from billing department while in store and same confirmation given of payment going through that was the 6of february. And now the 1st april telkom debits R804 instead of R599 and payment bounces because i left enough for the contract amount and the debit more & calling cust services to be told they added charges for that bounced payment of january which i was told it went through and telkom had alreasy sent me a bill by post showing payment and she says that only after 3days the system will pick up if payment bounced by the 3rd february and bill was sent already but then again doesnt make sense because on the 6feb i was in store i also have text from telkom to rate the service i got at the store as proof of date and now again the bank charged me for the debit bounce from my account.
