Forwarding Appointment Order

Dear Seniors,
Currently i am working as an Asst. manager(HR & Admin.) for an engineering company in Kolkata. Now i am looking for a propective career either in Delhi or in Bangalore.
Very recently i have received a mail from Decon Engg. HRD, Coimbatore. They advised me to submit my qualification certificates(xerox) along with a DD of Rs.2000/-. They also assured me on phone that job will be confirmed and there is no chance of rejection, only post will be suitable.
After submission of my documents along with DD, i received a Forwarding appointment letter from DECO-ENG, Coimbatore which is addressed to Viashnavi Associates, , Gandhi Nagar, Bangalore where i need to go for appearing interview.
Since i have no idea about this consultanchy(Vaishnavi Associates), i would like to request the seniors to give some inputs regarding this matter. Is there any chance of being cheated?
Regards

Dear seniors from Bangalore. Please provide your opinion if you about Vaishnavi Associates.

Dear Dino,
First of all in the current scenario no company or consultant is charging any money from the candidates. When they asked you the money, that time itself you should have asked this question yourself or in the cite HR for advise.
If you already sent the DD to the people who asked for it. By any chance you got their CBE number. If yes then call and find out the address.
If you could not find any of these company or consultancy then think that you are cheated.
Prior to sending any money to any company or consultancy, cheque whether the company is existing or not in the website of Registrar of Firms.
Regards,

Thanks for your opinion.
I relied only because DECON -ENG IS A REPUTED co.
If anybody knows about Vaishnavi Associates please provide me information.
Regards
