bad service

i just hate how Cell C has treated me like a ******** and call me a **** when I only wanna do a sim swap on my lost phone number, firstly why would they offer online service for sim swap when they will make it impossible for you to acquire it secondly don't they have a way of confirming you are the owner of the phone number than ask you questions they can't answer themselves. I am advising everyone not to lose their phones coz cell c won't give you your number back
