NO SERVICE AT ALL

We have ordered 2 Windows, a bath sliding door, some loose pieces of glass and a glass for the glass door from them. The 2 Windows and loose pieces of glass were fitted, then everything when down the drain. Bring the incorrect size for the glass door and the bath sliding door, then came back with the correct size, but the bath sliding door, were not ours that they forced in. Now we sitting with a dented incorrect sliding door, and they refuse to come and fix this. The glass in the door, they can't put the silicone properly, and they have broken our door handle. Unfortunately we have already paid them. And they refuse to do anything from their side. Even contacted the GM, and he is also as useless. The GM is Jack. They guy who "fitted" the stuff is Albert, and the sales consultant is Thelma.
