Frontgate, Splash, Grandin Road Defective products. No customer Service Westchester Nationwide

Purchased two sets of their Valencia Chaise Lounge Chairs. Four total. I brought the chairs out of  protected winter storage and one of the chairs had deteriorated and was not useable. Out of warranty so no return was allowed. When I wanted to purchase a replacement chair they would only sell me the pair at full price.  I don't need two more chairs only one.The quality Frontgate advertises is not there, nor is their customer service. Purchasing their expensive products is a RIP OFF.
