Cell C unable to perform a very simple task of updating bank details

<p>After numerous attempts, CellC has still failed to update my bank details. I have spoken to 3 consultants in 3 months and still have to pay for CellC not being able to update my bank details. This is the worst service I have ever received from any service provider. The consultants even claim to not be able to trace previous phone calls, although they are quick to tell you that calls are recorded. PLEASE CELLC, GET YOUR ACT TOGETHER. PLEASE RESPOND TO MY EMAILS AND UODATE MY DETAILS. I need to be refunded for the R70 i am being charged for a bounced debit order due to CellC debiting the WRONG account every month</p>
