Cell C deactivated my number and took data I paid for

Good day, I am extremely unhappy as Cell C deactivated my backup SIM with 1GB data because it is not in use, I was advised by Cell C to purchase a new SIM, RICA the SIM and give the RICA Serial number and they will reactivate my number. I was advised that the store would be able to activate it. When I went to the store, purchased a SIM and was advised by Store staff and then Customer care that I can't get my number back, then I spoke to a Team Leader and he advised I should call back in an hour when the SIM is registering on the system. No one can assist me with my getting my number back. But I was advised to purchase a new SIM and then I can get it back. My reference for the call was *** and was assisted by Nikosikosa. Now I am losing a 1GB data that I purchased and my number. This is ****************.
