R200 for a Sim Swop is ******ion!!

I have been a loyal customer with multiple contracts, for over 4 years now. My sim card was damaged due to a faulty phone and Cell C was nice enough to repair my phone, but refused to replace the sim card. I offered to buy my own sim card to proceed with a sim swop, but they still wanted to charge me almost R200. I was advised to go to my nearest outlet and the rudest consultant I have ever met gave me an amount exceeding R200. Please explain how I have to pay more than R200 if I am willing to buy my own sim card? For a few months now I have not been able to make use of services for which I am still being billed for on a monthly basis (and also, changes on a monthly basis, this month it is almost double what I normally pay, even though it is not being used). I feel that this is nothing short of ******ion and should be addressed accordingly as the customer care consultants are unable to assist effectively and do nothing more than the bare minimum to resolve my problem.

I look forward hearing from you.
