Cell c contract simswap impossible

I have been trying to perform a sim swap for the past two months for my contract number. The chip on the contract sim card has been damaged, I use the sim on router for data utilisation that means I have not been utilizing though paying for the past two months.

Here is my problem, I call 084145 for assistance and they transfer me to contract department and the call gets cut while I am holding. When I ask if I can't call contracts directly I am told I can do it using the contract number (damaged SIM number). The few times I have gone through to contracts I have passed the security check and put on hold then eventually cut off. I am so annoyed and inconvenienced as there is not even a single Cell c store close by. I don't have have money to payoff the outstanding settlement amount so that I can just cancel this contract.
