vriti infocom pvt ltd - Data Card Not Activated

Hi,
I had purchased the device online from tata docomo site on 25-11-2011.
The Person who called me redirected me to connect.india.com.

The device got delivered so late on 29-11-2011 even though it was promised that
device will be delivered within one hour of booking. In the bill was produced by Vriti Infocom Pvt Ltd. I had gone to tata docomo customer care but they are also telling they can't do anything about this. They are telling vriti is whole India distributers. If it is a fraud company why tata is still keeping vriti as its distributors???

Mentioning below all sales persons contact id with whom I had interacted with
Shantanu Viswakarma Person who called me after booking in tatadocomo site
gaurav.kumar1@vriti-interactive.com Person to whom I have sent the documents for address proof
The number from which I got the call is +912032601588 (This number never picked up) and the number to which I called for enquiring about activation is 09582104317. (This numbers hardly picked up.)

Each and every time I called they'll be telling device will get activated in one hour. But till today (19-12-2011) the device did not get activated. The verification was over on 3-12-2011.

The Datacard specification is as follows
Device IMEI is 359538037863806
MSIDN is 8983782961
SIM number is 89910371110130310818

I would like to raise my voice against this company and requesting you to take necessary actions

Thanks,
Sudha
