No feedback on network problems

I have been having network problems with my Telkom wifi since last year November. I have been complaining through logging several call with Telkom call center but they keep on saying they will send the technician but they never did. I called again on the 3rd , 6th, 16th Feb and today. I even went to Telkom store(Thomson- The consultant) in Irene where thy also promised to call back tomorrow. I'm paying R905 / month for uncapped wifi but we don't get the service which we were promised or signed for. We have to keep on reseting the router due to poor or no network. This must be fixed or the contract has to be terminated.

Can this matter be attended urgently because we have been paying for the service that we are not getting.
