Ebay.in — Keeping a product on sale even though it was out of stock and still taking the money for the same!

Address:

Gandhinagar, Gujarat

I paid Rs. 6443/- for a 2 TB hard disk from Infinity Retailers via eBay.in on 15/08/2015 and the due date for shipping was 20/08/2015. But then they asked for an extension of 4 days on 20/08/2015 requesting me, as they were not having the colour I booked that day, even it was showing more then 10 available when I purchased it.But I accepted their request and gave extension till 24/08/2015. Now again they are telling that its out of stock and they didn't shipped my purchased item which I have already paid for 10 days back from now. So now eBay.in cancelled my order today morning because "Infinity Retailers" didn't shipped my product before due date. And I can still see the same thing which I purchased is shown available on eBay.in site. Why are there joint venture fooling the customer if they are not having the product??? They have kept my money for 10 days without any reason with them and enjoyed the interest on my money. I am a normal living person and can't afford my interest getting wasted like this. As Rs. 6443/- is quite a big amount for an average income person. I want my money back APPLYING INTEREST of these 10 days please. So they will never repeat these for any other customer. Thank You! I request you to please take a serious action on them as the customer care was also not listening to me properly.
