Tata Consultancy Services — Onboarding delay

Address:

Kolkata

I accepted the offer on 31st January and my onboarding was on 22nd may but I recieved a call just 4 days back that it is delayed to July/aug.Already 105 days are over and I am worried what will happen if they don't give me joining before 120 days.I.am an experienced professional and it is difficult for me to survive without a job for 2 months.I have already completed notice period in my previous organisation.
Please help me on this.
