Very VERY bad customer service

I've been trying to do a sim swap for the past two days and each time I am told a \stories". I bought 3 sim cards worth R3.00 plus my time of standing in queues which has gone into waste. I just bought a \""fourth sim card\"" from Ackerman Store today and I am told that RICA *** has been deactivated by Cellc as it belongs to someone else. So they want to tell me that Cellc is duplicating the sim card numbers? This is so pathetic and unprofessional of Cellc if it the case. Now once again I need to buy another sim card which I don't what the story will be. It is a very frustrating situation that I am in . Cellc my get their systems in order and stop \""DUPLICATING THE SIM CARD NUMBER\"""
