What happened to customer service CellC?

I find having to rate CellC quite a difficult exercise....I have been a very happy customer for about 14 years but have received such bad service in the last couple of weeks that it overshadows the good.

I recently acquired my fourth contract with CellC for both home and business purposes and the service up until the billing has been excellent- in this regards I can highly recommend Ubedesha Brijlall (a direct sales agent) who had provided me with fast, efficient service and really went the extra mile to ensure my satisfaction, even after the sale!!

The issue however arose when I was billed incorrectly for alleged out of bundle spent...although I reported the issue and was promised feedback nothing happened. I reported to the call centre (spending up to 45 minutes on the phone at a time) as well as through their website and their customer service email. Apart from the electronic communication attempts- which I have had no reply on for 7 days, my calls to the call centre was met with unhelpful, sometimes patronizing untrained staff, very quick to blame shift to either colleagues or myself as the customer.

So all in all I found my recent experience of CellC's customer service to be extremely disgusting and upsetting, leaving a very sour taste having to retract my praise for them from family and friends. You guys have lost your stars with me!!
