trex deck boards review: Lowes 1

In November I went into the Lowes store looking for trex deck boards and at that time I spoke to a Manager. He sold me two bundles for $200 each, which I purchased on my credit card along with a delivery fee. The next day I was informed that I could not get them delivered and that I had to get refunded because it was a stocked item. I feel this is not my fault and I should get them for what the price I was quoted. I called the store and spoke to the store manager several times and I felt he gave me the run around. I called once again and he told me that he could not sale them to me for that price. He did not offer me an apology or a discount for all the trouble I had. On the day of the delivery I had contractors waiting to put the deck together. I feel the if I was sold the boards at that price then I should get them at that price.
