Free Yourself Go Elsewhere NOT Cell C

I have 2 Cell C contracts that I pay almost R1600pm for. Recently the Cell C sim card became defective. Been to the Cell C stores 3 times in the past 2 weeks. They allege each time that a sim swap was done and issue instructions to insert the card into the phone after 4 hours and if that doesn't work after 24 hours. After 3 frustrating attempts, it still doesn't work. I phoned into their call center several times and nobody seems to know what to do. How pathetic is that? I now have a contract with no service. I made the biggest mistake in my life taking a Cell C contract and I would advise that nobody should consider this provider. Their completely ***********. I am now intent on canceling this contract.
