Cell C Total Lack of Service

I have a back-up cell c phone number in a spare phone which is always on and charged, yet I hardly use the phone as it is my back up but with more than R500 prepaid airtime on. I had to do a sim swop some time ago when I got another new phone as I needed a micro sim for the smart phone. Cell c then went and disconnected my number. Yet it was always on, it was Rica, it had more than R500 airtime. Why? After days not reconnected nor received airtime back. Currently in Cell C Wonderpark. With customer care and no joy after more than hour. *** was just again opened. I was asked an alternative number to be contacted on yet again the consultant who initially logg original call for number ********** 847 logged it wrong. Still not sorted. I want a refund!!!!! Or my airtime back. We have received your query and will attend to it shortly. Your reference no is: ********** 842. An SMS will be sent to you when your query has been resolved. Cell C. Maria Molubi is assisting very friendly. Third party Tpha for cell c keeping us on hold with no joy more than hour.
