I purchased a shower tray and shower wall and on the same page was extras such a riser kit which to a novice kind of meant you need this. I had a plumber let me down so by the time I got another 6 weeks had passed and he said I did not need the riser kit. I contacted QS who said no they would not take back after 14 days. I explained why it had been so long and was told no, no, no. I asked to speak to the manager Ahmed told he was busy and would call me, never did. I am self employed is an business and understand cash flow, but also if your flexible you get repeat business. For the refund of £50 or so they would have got another order for my mother in law for some £700.00, guess what not now. DONT'T deal with them......!!!!
