Cognizant — offer not releasing and not responding for mails

Address:

603103

I attend interview on may 28, hr said everything cleared please fill cis i did that and again they send some link to take live photo etc i filled all. Hr called and discussed all details he said he will release offer letter that day itself since there is urgent requirement. But after that no response they are not responding for phone calls and mails nothing. They said resign from present company if you join asap we will thing about some more hike in compensation. I trusted them and resigned but they are not at all responding.

I am suggesting all please don't go for this type of fraud companies.
