ZS Compney run by one man call himself Mr Luqmaan, He is a dodgy guy. He is fraud. He will take you…read moreto into full confidence by showing his factory and some one else job without any references, Talking very nice in the binning before taking your money, He said he has German very high quality products, this is German, that is German, This is German technology. He made me fool because of his lies, His products are rubbish, Windows and doors are very poor quality, it's very weak during installation keeps breaking and after installation it's very shaky I'm dead sure Luqnaan and his windows fitters are not qualified fitter. He messed up whole house, He has installed some windows too small and some too big, he damaged whole my house and didn't complete the job. He has left the job half way. I had to get it done from someone else, Including too much repairing work. I made a mistake by paying him in advance. He took £4750 In name of advance and since then he keeps asking for more more money, He was saying otherwise my work going to be delayed because he don't have money to pay other party, every time he does little work asks for money. He took all money well before completing the job I ordered 3 bedroom house's all windows, kitchen door and complete porch, originali he has agreed for full job around £8,500 they increased £9,500. He had promised me that he is going to complete the job within 2 weeks and now been nearly 3 months. He was keep promising he will come in few days to complete the job but newer complete the job, now he is very abusive and says I'm not going to do your job do what ever you want to, I'm not scared of anything he is saying. Luqman took all money without finishing the job.

Thought I would use a local company with good reviews, up…read morepops Z S Double Glazing LTD, very quick to come round and strike a deal, so far so good....but when it came to replacing the windows and fitting the fascias it all seemed to be rushed and very messy. When they said they finished the work it was dark and from what I can see it looked ok but the follow day when checking it was not completed to an acceptable standard. I have called and text a number of times with no response and when chasing I have been told now that "We dont have the staff" but my question is why doesn't Lukman (company owner and hands on) come round and address my outstanding issues/concerns? Would I reuse Z S Double Glazing - NO! Would I recommend Z S Double Glazing - NO!

I think we got caught in the sales pitch into trusting, the installation was quite smooth, but days…read moreafter the door stopped working and I have been chasing for about 2 weeks to get them to sort it out, the latest one (to which I am on the phone with them now) was that they would be with us between 08:30 and 13:00, so the family got up and was ready from 08:30 and guess who hasn't shown up again! In short, the door lock stopped working properly after a few days, a vent wasn't installed that should have been and the door numbers never arrived. They seems nice enough people and maybe I've been a difficult case but it a case made difficult by them. It is me chasing and it is my family that has had to stay in for two days so far. In short I would say don't let them into your house, its not worth the risk and there are other window fitters out there.
