I have for 6 weeks been trying to change from CellC to MTN, but Glocell is not porting the number as requested. Apparently after number out call to the customer service I got down to the bottom of it and Glocell requires a termination form to be filled out. They promised to send it multiple times but didn't bother to do so. Finally I managed to keep the customer service on the phone line until I had received the form. Then explain that I have to wait another 30 days for the cancellation of the contract, even after they been unable to provide the required form for 6 weeks. It's feels like the company is holding you hostage to contracts and is not providing you with the necessary forms to end the contract.
