Frustrating and Unresolved Service Experience at Vodacom!!!!!!

I am extremely disappointed with the service I've received from Vodacom!! Over the past 3 months, I've visited Vodacom four times, had email communication, attempting to change my business account to my personal name and update my bank details. My last visit was at the Vodacom store in Nicolway centre, where I completed all the necessary paperwork. I was assured that everything had been processed. However, despite these repeated efforts, nothing has been resolved. Every month I am told my account has not been paid, which is not true given my attempts to correct the information. It is frustrating and unacceptable that after 3 months of trying to resolve the issue, nothing has been done!! After being a loyal costumer my whole life I expect much better from a company of Vadacom stature!!!!!
