Dear Sagar Rana Ronny,
You had made an agreement with a job consultant to pay his fees provided if you get a job. You got the job, and accepted the offer letter from the employer but did not join the company. But then the question is why did you do it? What were the compelling reasons for refusing the job offer?
Look from the consultant's point of view. All his efforts of searching for a job candidate, organising the interview etc have gone in vain. Is he not entitled to get paid for the work he did?
You have written that "he have a paper with my signature". What kind of paper is this? Is it a contract enforceable by law? If it is, then the consultant could exercise the option of filing a police complaint or suing you.
Well gentleman, exercise discretion. There is an English proverb measure twice and cut once. Possibly, you had taken cognisance of the proverb before entering into an agreement with the consultant.
Thanks,
Dinesh Divekar
