Bad workmanship from Frontline Shopfiters

I had my kitchen counter top replaced by Frontline Shopfiters. After the insurance paid them it took about 3 weeks if not more for them to come and replace the counter top. Day after day the excuse was can only come after 14h30 in after noon or weekends and the flats I stay in has a rule no work to be done after 17h00 weekdays and 13h00 on weekends. Then I was told the company do not have closed vehicles so if it looks like rain the can't transport the top. Now I'm asking how can a company not have transport that suits the type of work it do. Eventually the top was fitted and not complete because the fitters did not have enough silicone. He returned the next evening to complete. I showed him that the sink was loose infront he then said he will put silicone in. When he left he told me not to move the sink so the silicone can set. Next morning I checked and the sink was stil loose. I lifted it only to see no silicone there not even a drop after I was told that he did it. I then contacted him and told him he is s **** and he did not place silicone there he answers that he did. REALY!! He then said he will return this evening and fix it. I told him he must stay away. Because after not bieng able to use my kitchen for two days i had enough.I then removed the sink and fixed it with silicone the way it was suppose to be done. I will never use this company again and will never refer them to anny body.
