Horrible people to deal with supreme shower enclos

I met Pieter in October 2014 for glass splash backs. He assured me he knows what he is doing. I paid him on the 7th of November 2014.. On the contract it said glass will be delivered in 18 working days. 2 months passed and still no delivery of glass, every time I tried calling them they wouldn't take my call and when I reached them they were always full of excuses as to why the glass was not delivered. The day they finally said they will install on the 30th of January 2015 they did not show up. On the 2nd of February they promised to come to install, there van broke down and they couldn't come, excuses after excuses. They finally arrived on the 3rd of feb with the glass they installed it very poorly done and the glass painted the wrong color. I tried calling them to remove glass but all phones off and no response from them. When I finally got ahold of them they refusing to remove glass and sort out for me. There manner in which they handled the situation is very unprofessional. Please people be aware of supreme showers, don't use them for shower doors, glass splashbacks, or anything glass related. They are an extremely horrible people, Pieter, Babs and Gert.
