why is my cancellation still not done

Telkom Telkom, where to start, cancellations was requested on the 16th of June. And still not cancelled how does that work?? When phoning the call centre 3 times and getting NO joy, because they just tell you they can not do anything, \go to a Telkom Shop"how can a company as big as telkom not even be able to do cancellations? I will never in my life be interested in Telkom again or recommend it to anyone. You give the worst service possible. To top it all off i paid for a data service that never worked 100% and Telkom could not give a resolution. Please get this contract cancelled."""
