No WIFI signal but still being debited

Telkom is disgusting I haven't had Wifi signal from November when I took out the contract. I laid complaint at the Ballito branch that took me 45mins for a consultant to assist me. They sent out a technician and he said he will send the report to Telkom but did not receive any feedback. A month later another technician comes and ran tests and said Telkom will sort out but no calls or feedback and still no Wifi signal. I want my money back and want this waist of time WIFI to be cancelled. It's shocking the service you provide for such a big organization.
