Magnet supplied us with windows, which became drafty and were difficult to open and close, one is now completely jammed. I have repeated asked for someone to come and look at them under their guarantee. At first they said it was an issue for Jenweld. When Jenweld were not the suppliers and the supplier they used at the time is no longer trading they started to ignore my correspondence. I have been trying to get a resolution for circa 6 months now and am no further forward. It seems they think if they ignore my complaint for long enough I’ll go away. Very disappointing.
