I'm flying tomorrow (03/11) to Bangalore for the case "booking", whatever that is. I'm also taking proofs of transaction provided by another affected person who contacted me, and try to add him as a joint complaintant.
However I'm not happy about just going to consumer forum, so I will also go to the Cyber crime police station in Bangalore tomorrow, with my own complaint and the printouts of complaints posted by other persons on the internet. I request any affected person to email me at kannanj@microsoft.com with any proofs of the transactions like
 Order page at 3gstore.in, or order receipt received by email.
 Any email conversation with 3gstore.in
 Credit card statement or Savings bank statement showing the transaction.
 Credit card statement or Savings bank statement showing the absense of any refund since the transaction date.

I can provide these to the police so they can take it seriously. I will check email during the day tomorrow.
