I received an offer letter from a Third Party and was supposed to be deployed at Infosys on 3rd November. I resigned on 31st October. However, on 1st November, the Third Party informed me that the joining date had been postponed. They are unwilling to pay me until a new joining date is provided. Recently, they confirmed that the position is on hold until December and advised me to search for a new job. Since I was on their payroll and never visited the client's site, they refuse to compensate me. I am considering filing a complaint against them. Can you please advise me on where to file the complaint?
