Can I take any legal action against and employer continually extending my layoff/termination date?

I work for a bank and they are currently going through what they're calling a transformation. This included some layoffs, new hires and branch closures. My original branch closed January 31 2019. The original severance agreement that my coworkers and I signed said that our release date would be February 2, 2019 or later. They then verbally informed us, about 2 weeks before, that the date would be moved to May 1 2019. However we did not receive this in writing. I was moved to a branch that is a hassle for me to get to, and that has later hours than my previous 1. I am hearing now that they are going to try to extend the date again until fall, maybe September or October. I feel as though they are using us and hanging these severance packages over our heads. It feels wrong morally/ethically but is there anything legally that I could do about it? I'm unable to look for other work or spend time with my son like I'd like. I can't afford to keep being held in limbo like this.
