Sadv bad poor service internet providers

I signed with sadv for a home fibre and two days ago they came to install, I had no network on the 1st day and no one even bothered to call and explain the problem, the next day I decided to call and find out why I don't have internet connection for 2 days, it took me an hour and half to finally talk to an agent and even after I spoke to an agent I still don't have network connection and tomorrow it will be 3rd day, I have paid u guys, I want my full refund since the service u supposed to provide to me u haven't and u keep making excuses that u have network issues around my area which is protea glen and that is not my problem, poor service u have, u don't even have whatsapp group that is available and convenient like fly cool. I am going to sign up with fly cool they are better than u, just pay back my refund.
