We are really sorry to hear you were disappointed with your purchase.
Buying online can be tricky without the ability to look, feel and touch in person, which is why we put a lot of effort into our product descriptions. The size of the mat is very clearly stated for this item.
Because we want all of our customers to be super happy with their pieces, we also have a 100% satisfaction guaranteed returns policy. As it says on our Refund Policy page, you can contact us within 14 days of your purchase if you are unhappy to receive a full refund, exchange or credit.
