Extremely disappointed in CellC.

I done my upgrade with CellC on 01/12/18 and i have problems with them ever since. I changed one of my contracts from a handset to a laptop and i cannot tell you how inconvenient this process has been. I was told that i would have the device for free until end of February 2019 before i start paying for it. Needless to say they charged me for the device from 01/12/18, without changing the premium (the handset was more than the laptop). It just went from bad to worse, i cant even keep up anymore. It turns out the incorrect package was loaded on their side and they started charging me for out of bundle rates, when my package was actually supposed to be limited to 4G per month. To add insult to injury they were giving me only 4G since December, but charging for the open line (not sure who was making use of the open line when i was restricted from doing so). In February i was debited R349.00 more than my premium and when i called in to inquire i was told that they would lodge my complaint and someone would get back to me within 48hrs. 2 weeks thereafter a consultant called me advising me that i was due a credit of R179.00 because the wrong package had been loaded. I then asked him where the balance of my credit was and he said it went toward the out of bundle rates (which i never got to use). The call center manager had advised me i would not be charged for that (when i called in initially in February). Well of co**** it became another query which would be attended to in 48hrs. It is now March and i received a message to say please contact our customer center regarding the issue, when i did the call center agent was stunned that i was asked to call in because my query had been closed. Never received my credit neither and my query is still unsolved. I also have messages that show there is two packages activated on this account. One bundle and one monthly bill allocation. I wonder who is making use of the monthly bill allocation. Extremely disappointed in CellC!!!!!!!!!
