Pilot Gas Services Scotland

I hired Pilot Gas Services Scotland LTD to tile my kitchen for me. I have never seen such a poor job in all my life the work was substandard, shoddy done by a real cowboy l now have to pay another firm to rip everything out and start again the job cost £350.00 for a small tiling job, now l am having to replace the window sills as they also damaged them both. I had the work inspected and was told the tiles used where the wrong ones, and the guy didn’t finish the job, the tiles used for the job where only worth £20.00 the cost of redoing the work l have been quoted £750 + vat. As l rent flats out l also hired them electrically test equipment around the house when l asked the the guy about his credentials he told me he was not an electrician and that he could only check plugs, this was not what l asked for l asked the company for an electrician not a guy to test plugs. I will never use these guys again for their unprofessionalism avoid them at all costs. I did send the company a letter of complaint but never received a reply but l was expecting that anyway.
