GOO2O.com (O2O Technologies Pvt. Ltd.) — Not refunding 70,000 INR paid for an item not in stock even if displayed as available

More than 70,000 INR not refunded by the company in charge of the website goo2o.com, O2O Technologies Pvt. Ltd:

On the 22nd of March 2012, I purchased a 71,757 INR professional camera lens from the website LD Shopping Store (www.ldshopline.goo2o.com). I've been redirected to the website http://goo2o.com, of the company O2O Technologies Pvt. Ltd. , to transfer the money through Net Banking. 5 days later, even if it was highlighted on the website that 5 items were in stock, I received a call from Goo2o to inform me that the item was out of stock, followed by this email:

After I sent my account details, I called them several times to check the status of this refund, as I still had not received my money back on the 5th of April, and they told me that the reason was that my PAN number was missing. I immediately provided it and received this email:

Dear Mr. H,
Good Evening!
Thank you for providing your PAN details.
We have already forwarded your bank account details to our accounts department for refund processing and the fund will transferred in next 2-3 bank working days.

2-3 bank working days later, the money was still not refunded. I called back, the person in charge was not available so they promised to call me back and sent me this email:

Admin, Apr 12 21:40 (IST):

Dear Mr. T,

Good Evening!
We regret for the delay in response. As per our earlier communication with you, your refund request is in process and it will take 2-3 more working days to process the payment.
In case of any query, you may call us at our customer support no.[protected].

Since then, their phone numbers are not reachable anymore, nobody ever called me back, and here is the only message I received:

Admin, Apr 13 20:38 (IST):

Dear Mr. T,

Good Evening!
We apologies for the inconvenience. We are sincere about the refund process and it will be done shortly as we are getting some technical issues with the e-net (NEFT) transfer.

The NEFT transaction to transfer them the money took me 5 minutes, while today, on the 17th of April (22 days after the order cancellation), my 71,757 INR have still not been refunded, and I still have no news about the company O2O Technologies Pvt. Ltd. that is behind the website goo2o.com.
Not only their behavior is extremely unprofessional, but their honesty is highly doubtful.

H.T.
