****ty service that has stupid solutions

On the 25th of June I purchased 20 minutes however they were not working when I recharged and made a call instead of deducting from the minutes it was deducting from the airtime I then gave cell c for them to assist the started troubleshooting the phone and they found that the issue was the minutes then instead of them refunding me they tod me that the back office can do that so they will log a case of which the agent did I then requested to speak to her manager by the name of nolwazi shezi which she was no use she told me the San thing the agent told me on the 26th I spoke to nompilo which she is a manager as well she told me that my case is still running she will try and ask the back office to call me after 2hours which they did not call today is the 27th I called and they still told me that the case is still running why do we have a customer care line which has no help for us if they have a system which they cannot use to service their clients why are they there.
