CELL C has Terrible Customer Service. This WILL affect every Customer at one time or another.

I have tried repeatedly to solve a Recurring Data subscription with Cell C whom have been my service provider for many years. I have been purchasing a 10Gb recurring bundle for my mobile at R550. Last month it would not allow me to subscribe to this service so I phoned 140 to speak to a representative. The lady solved my problem at the time and she converted the loaded R550 to the 10Gb bundle. What she also did without my knowledge is deactivate the service so that when the following month arrived for a new recurring purchase that should have taken place automatically, the money I loaded two days prior to the 30 day expiry for this purpose was used up instead of being converted to the 10Gb data bundle. I have phoned and explained my story on three separate occasions each time hearing from the representative and on the last occasion a manager that they understand and will listen to the recording conversations and get back to me with a solution. The manager I spoke to said they would most likely reimburse but would get back to me after 24-48 hours. They saw on their system that the previous representative has cancelled my recurring subscription. Another lady I spoke to said that I needed to phone in every month purchase and convert my uploaded airtime into the 10 Gb- this is untrue as I have done this several times in the previous months before. The second time I phoned the lady told me that they have no logged case for the first time I called but they said they could still listen to the telephone call. I have been told on each occasion that they would get back to me within 24-48 hours. I have not been called back on ANY occasion. This level of service has left me extremely frustrated and I have been purchasing extra data bundles that I WOULD NOT HAVE PURCHASED for this month as I would have had the 10Gb bundle. I keep expecting Cell c to call and resolve this issue. I am now going to buy ANOTHER 10Gb bundle manually using the *147# route and I have now spent far more that I would have for my budgeted internet and call time this month. I phoned yesterday and today but the 140 number says it is unavailable or is experiencing high call volumes and cannot take my call but suggests I email. I don't know what else to do and I am considering leaving Cell C for their poor service and NO ATTEMPT TO GET BACK TO ME. I cannot help but feel severely frustrated when their is no one I can speak to about this. One is promised service and this SERVICE IS NON EXISTENT.
