Cell C unable to deliver to it's loyal customer

I have been a Cell Customer for 13 years and have had repeat issues with my billing however this is the first time i have not had my bill resolved and the matter has been on going for 2 months.

My bank account was debited in January yet cell c did not allocate my payment to the account in question in February they double debited me and was unsuccessful, i then realised there was an issue with my account and notified them i also send my bank statement proving they debited successfully in January.

No action has been taken by cell c to rectify my account all they seem to do is charge me penalty fee upon penalty fee with no resolution or rectifying my account to the correct bill so I'm able to pay this bill up to date on the correct amount due.

I am very disappointed and think cell c has lost their credibility. I'm very dissatisfied your agents are not well trained, your SLA on service delivery is never met and your staff at the Durban Gateway branch are rude and not helpful.
