I got selected for one company, they took all my documents and they are not releasing offer letter, they made me to not accept other companies offer also, and wasted my time for 1 month, now they are saying it's only one month right, they are not picking my calls, after making 20 to 30 calls for 20 days they picked my call and saying what is ur problem,They made me to lose other companies offers and now they are saying it's not my problem, during the documentation they harrassed me like anything if u don't submit ur offer will be cancelled like that but now they are not even responding, it's very bad of there part, pls don't trust this consultancy especially recruiter mounika, she will talk nicely when she have work with u,if not su have to face her rude behaviour, don't trust this consultancy
