Cognizant — Office letter

Hi,

I attended the interview in cognizant bangalore on 23rd january, also selected and got confirmation in mail within 1 week.

I also got a call from one of the hr stating that the offer letter will be released in the next 7 days.

But now almost 5 months have been completed and till now i am keeping the same with cognizant hr person by mail and call, there are no updates from anyone.
Only one reply i received from hr cognizant that 'the position went on hold ' on 15th may while i got few interview calls for the same position last week as well.

Please help me out regarding this matter and try to confirm the same as soon as possible because i have been waiting for 5 months.

Waiting for your reply asap.

Thanks & regards,
Pramod kumar,
