Not receiving calls

My phone stopped receiving calls on the 06th June 2019. I picked up the problem on the 8th of June and phoned the call centre. They gave me reset USD codes to use and it didn't resolve anything. I phoned them back again the same day to say the codes didn't work, they opened a case and said it would be resolved in 24 - 48 hours. I then received an SMS on Sunday afternoon 9 th June saying my issues had been escalated and would be resolved in 24 hours. Since then I have spoken to 6 different customer care people, each one has given me a different reason as to why this happening and a different promise ranging from "it will take another 24 - 48 hours " as of from Tuesday afternoon to "the problem has already been resolved, just switch your phone off and on again and it will work." We eventually asked to speak to a manager, Ntombi told us to do a SIM swop and a different manager Nqueile said it's a network wide problem they are resolving. The answers we received from Cell C were inconsistent. and the problem has still not been resolved. Even two different managers gave two different answers! (one said do a SIM Swop and the other said it's a nation wide problem.) So there are two problems here: cannot receive any calls, and staff that are too *********** to know what is going on (if it is a network wide problem then surely the staff must know. The reference numbers i have are: ********** 342 , SD832395, ********** 730, ********** 739.

This issue needs to be resolved by Cell C immediately, the service given during this time has been disgusting.
