Horrible experience

I've had a nightmare experience with Brighton Mutsvanga ***) , whose apparently an installer. Came to my house or sent people to my house to install the new Explora, add extra view and connect my streamer to the Fibre. I was R1800.00, no connection to the streamer. One guy said they don't know how to do it. On top of that they stole my old Lnb. When I phoned them after they had left, they deny any knowledge of my old lnb. I phoned this Brighton guy he asked me to call the team that came out to install. They then some that they forgot to leave it with me. Fine I looked up on where they were working my wall had massive dents were their stepladder was places and my light was hanging on the wall. I phoned this Brighton single everyday for two weeks, he kept making promises every single time until I threatened to contact dstv. He has now promised to pay me for the lnb and damages. I'm still waiting. Please help
