My sister was appointed by a Bank for the position of HR Executive. She was sent the offer letter which she signed. However, suddenly the employer bank mailed her that her joining date is kept on hold indefinitely. We waited for sometime and tried contacting them through emails and phone calls. Finally, they replied via email which said that the candidate can look for other opportunities. My sister discarded another opportunity for this job and now these people are behaving in such an unprofessional manner. We want to sent them a legal notice claiming compensation for her time which they wasted and for the loss which she bore due to their acts. Please help.
