BAD CUSTOMER SERVICE

We have purchased/installed a one year contract for a wifi service in our home. From date of installation we have made numerous complaints to the company about the problem we are experiencing from their service. The network is very poor and not clear and stable from date of connection. The network freezes on every programme that we choose to use or view. They had come out to fix the problem on 4 occasions, but to date the problems still exists. I have lodged telephone calls for them to come out and sent a email on the 09/01/2018 to fix the problem and have not had a response. I have been paying R1000.00 per month for something I cannot use. I have now re-connected my DSTV to get actual viewing and paying extra money on viewing services..
