Pathetic service

I have been to countless Telkom stores in assistance to cancel a wifi contract that is even expired.Apparently they don’t cancel contracts in stores anymore!I have called the customer service lines and after the consultant says they are accessing my profile and put me on hold, they cut the call.This is so frustrating because all these consultants do the same.How am I to cancel this contract ?? This is becoming ridiculous, Telkom really needs to do something about this
