WALMART.COM Ordered a tv, had to wait 2 weeks for delivery, never delivered, called they said product not available Hobe Sound Internet

I bought a tv from walmart.com. They said it couldn't be delivered for 2 weeks. I waited the two weeks and no tv. I called them and they told me that the tv was out of stock and I could not get it. I paid $900+ for it, waited all this time and now no tv. I bought it online because it was $300 less than the store, though the store had several at the time. They did not even have the decency to notify me that I wouldn't be getting it. they just let me sit and wait for something they wouldn't sell me anyway. This is the second time they screwed me. I bought a lap top from one of their vendors, when it started acting up I called walmart.com, they told me I had to go thru the vendor that wanted so much to return it it wasn't worth it. Walmart the store is good,but, they need to do what best buy and others do. when you buy online it should be the same as in store. Now I have to wait for walmart to contact my bank then wait for my bank to refund the money, without a tv. this is unfair.
