Deal Dash online auction scam Internet

I started with DealDash 10/22/12 and won a few auctions early on.  One of the first auctions was a sushi making kit.  I received an email stating the item had been shipped.  About 3 days before the estimated delivery date, I received another email stating the item was out of stock and I could choose between a 50 dollar gift card to walmart or amazon.  I chose the wal mart gift card.  That was mid november. Still haven't received the gift card. 

Then on 11/20/12 I won a 100.00 gift card to Texas Roadhouse.  The estimated delivery date 11/18/12-12/11/12.  How could it be delivered 11/18/12 when I didn't win it until 11/20/12.  Either way, I still haven't received it.

I have contacted customer support several times thru the link provided on the site.  I received one response from them regarding having to choose an item to replace the sushi making kit.  Other than that one response I haven't received a response from any other complaints I have sent. 

I did notice that my dashboard says that the Texas Roadhouse gift card was shipped but I never received an email stating this.  Does it make a difference?  I don't think so because on the 2 items I am still waiting for, the dashboard says that both were shipped,  I received an email that one was shipped and yet I haven't received either.

I am still waiting for both of these gift cards and am very angry that reality is I may never get them.  Deal Dash should be held accountable for not responding to customer complaints as well as not providing the items won in a timely fashion.  I have to wonder if they purposely don't respond to complaints hoping that people will just give up.   They should not get away with not responding to customers.
