Cell C, enabling *****!

Yesterday evening, I suddenly had a "no service" status on my phone using a cell c sim. I was out of town with poor signal so didn't think much of it until some strange activity on my bank account. I had no phone signal so could not investigate this but as soon as I got hold of a phone the next morning, I called the call centre to inform of suspected *****. I was told categorically that no ********** activity was evident on my account and that either my phone or sim were faulty. Only when I got to a cell c store 6 hours later was I informed that in fact, a sim swap was done on my account the prior evening. All this time, ********** had access to my phone to receive one-time pins, etc. This is nothing short of gross negligence and serious action should be taken against *********** staff providing false information!
