Awful service and deception.

Treated appallingly at Cresta Homemark by the "manager". Backhanded and argued. Obscure issue about a signature on the receipt and I must know what that means. I was expressly told when sold the item I could change it but as it was on promotion I could not get a refund. Extreme rudeness and arrogance and no helpfulness from the "manager". Please avoid. Always get real poor service and staff not knowledgeable about products at all. Do consumers have no rights at all????
