Contract Sim-swap frustration

It's been full 2month struggling to get hold of Cell-c customers care regarding the contract Sim-swap, if I manage to get hold of the I will have I would have to go through cellc insurance then they transfer me and the called will get cut before finding assistance. I have sent them several emails I managed to speak to their consultants from prepaid department as they told me they can't help me in their department. I have to be assisted to contractor department and I told them am struggling to get hold of them. They promised to foward the email to that contract department so they can get hold of me. Till this day I haven't received any call from the contract department the calls am receiving are from prepaid department. And am so frustrated as now I'm paying for the benefits am not using and I'll be continuing to loose. Am really disappointed with their service lately as you can't get hold of them on the calls. It's either you would stay on the call waiting for them to answer for an 2hours when they get answer they call get cut, you can imagine that process of having to wait again.
