100Bestbuy.com — Fake display on Website

I had ordered an RR T-Shirt from the website on 6-Aug-2013, below is the link, to gift it to my friend who was leaving on 15-Aug-13.

Though there was COD available, I opted to pay through credit card. The payment was done and the amount got deducted from my account and received a message that they are shipping the item

After 7 days I went through my mails to check whether they have shipped but I found none, and so I wrote to them on their id i.e. [protected]@100bestbuy.com
but never received any reply. Finally I decided to call them, but was never able to reached the helpline number, which for some reason is always congested, after N number of calls finally I was able to get in touch with a person who told me that the item is out of stock and he will ship once it is available (and was about to keep the receiver down) then I told me the reason for my purchase and asked him to refund the amount since it is not displayed on their website whether the item is out of stock. He said that the payment will be done through check, after lot of argument I agreed.

But till date 2-Sep-2013, I have neither received check nor any confirmation from their team that the amount will be refunded.

Since my purchase was only worth INR 483 so it is not a huge loss, but the amount of time spent on calls and endless email follow-up is really painful. I would never recommend an one to use this website, they are bunch of fakes.
