Terrible customer care with no accountability

Supersonics customer care is appalling. The upgrade of my fiber line from 10Mb to 50Mb took two months to sort out, all the while supersonic charged me at the higher rate. I called numerous times, each time a different representative promising to sort out my upgrade and keep me updated with my progress... but each time nothing happens and I received no updates. Only after putting in my cancelation request was my query resolved. Only one Supersonic employee is the reason that this review is three stars instead of one: Ntsiki Dube was able to assist me in an efficient and effective manner all the while keeping me updated with the progress of my case. She kept on top of it and made sure my case was resolved. She should train the rest of the customer care staff on how to actually resolve cases.
