i to have had a problem like yours, it was a little different, but the sm e end results. they tryed to screw me 2 times. dispute the transaction with your credit or debet card company, just explain, what the company did, they should be able to get your money back real quick. they can push us the consumer around, but they are no macth for the card issiueing company. let your company do your biding, they will get your money back, good luck, been there myself.
i also had a problem with a 37'' tv from that company, it stop working 2 months short of the end of the waranty. it took the place they told me to take the tv to, almost 2 months to fix, they replaced everything inside the tv. i cant understand why they didnt just give me a new set. the repair shop said it would have been cheaper to just replace the tv. one month after i brought it home, with no waranty any more, the screen has a blue line running from the top to the bottom. no waranty, im screwed, im just waiting for it to stop working altogeather, i used to like that tv company, not anymore, there junk!
