Cell C should be escalated to their shareholder for bad service

I have requested that you fix the error on my account and the call center notified me that they would escalate it. Now when i call Cell C i am transferred to the collections department and they do not pick up the phone. The last reference number i received was ***. So in short, You owe me R1300 because the discount that has been on my contract for the last year was not app****. Then you need to fix your system stating that i ow you +-R60 as you did take a debit order this month.
