Products misrepresented and of poor quality.

According to their ad, we purchased Dimple Floor Tiles which were listed as robust and 7.5mm in thickness. When these arrived they were 4.5 mm in thickness. It was the thickness of the tiles (7.5mm) that attracted us to make a purchase. We were cheated and misrepresented which is unacceptable. The last three times I have made a purchase with this company the goods either broke or did not work. I do not recommend any of their "specials", no matter how enticing they look. Impossible to get a response from the vender, even after 5 emails!!
