Cell C: Sim Swap

Hello Peeps, I am having a terrible experience with Cell C, Customer Service and in-store service. I lost my sim and got a new sim and app**** for a Sim-Swap[To Keep my old number].

They Say The Details I am giving is incorrect and should go in-store and explain my situation.

I Get to the store(Cell C Cleary Park] and they tell me that i should phone Customer Care, cause they will ask the same questions.

The Store clerk told me that she can not help me cause the 3 numbers i gave were not correct and that she can not assist me with giving me back my sim number. I Asked: Can you see that the number belong to me and I told here the phone that it was in and the exact time it was removed from my phone, last recharge & personal info and they still cannot give me back my number.

I do not know what to do next ...
