I bought £1500 worth of floor tiles and provisionally ordered a £50 adhesive. I called and asked for confirmation that I had ordered the correct adhesive and was encouraged to upgrade to a £90 tub. When we used the adhesive, it did not dry. When I queried this with dctuk I was told that it was the correct adhesive but my floor was wrong. I didn't need to change the adhesive, I need to change my floor. When I asked for a refund on the adhesive to mitigate my costs I was asked if I had the advice in writing... Do NOT trust anyone from DCTUK to give good advice nor take responsibility for bad advice. Useless and dishonest.
