Poor Customer Service

For a few months now i have been trying to get CellC to reverse ******* debits on my CellC contract , after lots of frustrating correspondence , they have finally reversed the ******* charges but still continue to charge an extra fee for RD charges as i instructed my bank not to honour any debit order that is not as stated in my contract ., So i will continue to pay this account in cash payments until they remove these erroneous extra charges from my account and they only charge as stipulated in my contract . contact :***. This info was given to their staff on several occasions and if they do not attend to this within 7 days hereof , i have been advised to complain to Icasa .
