Paying for Wifi for THREE months now for nothing

Telkom made a mess up with my account and there is NO way of getting hold of them. A lady phoned me, she said she will phone me back. She never did. I went to the branch, I never got a call back. I even left my details on the website, NOBODY phone back. I have been paying for my account for THREE months now, Telkom even double deducted, but my Wifi is still cut off!! I was never in arrears. When I asked to change my paydate this was not done either!!! I am highly upset with the service and the fact that there is just NO WAY of getting hold of Telkom except by complaining!
