Bad service

While upgrading my contract over the phone two new sim only contracts was added on. I have been trying for 3 weeks to get it sorted or cancelled. as per the consultant I agreed to it. I have 3 Cell C contracts already. Why would I agree to two more. I am being transfered from one department to the next. Yet still no answer as to how to cancell the contract. No device was even sent on the original contract. One one of the existing contracts watsapp bundle was added and bill protection which I also did not agree to. Please be vigilant as to what is happening on your contract.
