I bought a pair of aluminium windows for my loft conversion, one single piece of glass, one split with the top portion opening. When I ordered, the estimated delivery time was 3-5 weeks. A week after ordering I called to change the size of the transom portion of one window, as there was no way to do this on the website. I was told this wasn't a problem. 2 weeks after ordering a delivery date was "confirmed" for over 7 weeks after my original order date. 7 weeks and 1 day later the windows arrived, partially. One of the trickle vents was broken beyond repair, and 2 of the pieces of glass were the wrong size. The new glass was scheduled to arrived 10 weeks after the original order. It arrived late. When the glass did arrive, only one piece needed actually turned up. Does it take Einstein to realise that if one portion of a split window is wrong, the other is wrong too? So here I am, 10 weeks after Just Value Doors took £1600 off me, I have one window installed but without a trickle vent, and one window with a trickle vent but with no glass. Does this smell like success to you? Oh, also, because the glass needs to be fitted externally, I've had to keep my scaffolding up for an additional 3 weeks, costing me £150. Who knows when the next piece of glass will arrive. Pray for me.
