TCS Vs Tech Mahindra

I am leading a decent life. Suddenly a Cyberfraud Happened and lost 70L INR. All of them are loans. Monthly EMIs including Home loan was 1.7L and the duration of loans was ranging between 3yrs to 7yrs. We were able to clear 40L through selling property etc. Now the EMI left is 91K per month for next 4yrs. I got an offer from TechMahindra with 50-60%hike. Currently working with TCS at 22LPA with 15yrs experience. Expecting 10L getting released from banks which were held by Cyber crime, but not sure when is that going to happen. If I get those 10L, the EMIs would further reduce to 70K. Considering Job security and exposure as my priority, is it ok to revoke resignation from TCS and deny TechM offer. Please advise.
