Glasfit review: Windscreen fixed after 4 trips there

My windsreen got hit by a rock and my Insurance send met to GlassFit. I went to the Montague Gardens Branch. Took my car there on a Saturday after my claim has been approved. Got my car back, did everything as was told. 3 Days later it rained and the water POURED into my car in the middle of the windscreen. Everything was soaking wet in 'n a couple of minutes. I took my car back the next day and the guy just kept on saying that it was impossible. So one of the workers who worked on my car blamed rust. My car was at the Panel Beaters last summer and all rust removed, so if the Panel Beaters didn't do a good job. surely my window would have leaked before GlassFit replaced it. A bit of cilicone was sprayed on the inside and I was send away promised that it is fixed. But it was still leaking. Took the car back again on Saturday, they removed the windscreen again and re-did the whole job. The next day the strip blew off. It was just put there, no silicone or anything to keep it there. So I had to go back for a 4th time! No apologies, nothing, just told me to move my car into the workshop. My petrol tenk is empty from the 4 trips there, my car is still wet and smells like mould.
