Cellc service is pathetic and the staff they hire

I have a prepaid number that's being used by my nephew which I wanted to do a Sim swap on, his iPhone that I took out with Cellc got damaged and he cannot remember how much he last recharged with and the frequent numbers dialed. I called Cellc customer service and I failed the security check and I was advised to go to the store with ID. I am just from one of your store where I was told the Sim is not going to happen and I was told we'll done by saying I am going to take this to hello Peter by a consultant named Thulani Mayindi and there after ignored me and moved to the next customer, can't wait to cancel all my 5 contracts with Cellc.
