poor cellc service

we are aware that Cellc its bankrupt but it must respect clients when it comes to billing, i have an agreement with cellc to debit my account R258 every month on the 1st.

Cellc debit the day they want and if they don't find money, its my faults so i must be penalized R70

Some other months they debit and the money is reflecting on my standard bank account to be paid to Cellc and they refuse by saying, "they didnt get the money". This month its out of control, they deducted R452 of which we agreed about R258

This must be reported to Communication Ombudsman
