I use to work for a trucking company and this company is now blocking me from receiving unemployment and is reporting false information to other trucking companies I apply for. Can they do this to me?

I had an incident in 2018 where my truck slid down a dock on ice while park, then another incident in June 2019 where I backed up in a dock and scrapped the side of my truck and reported to claims. I was then fired behind it. Now this company is reporting false information to other trucking companies when they call for a reference and they fought my unemployment stating I didn't maintain a good driving record and driver licenses when I have a good driving record and my license is in good standing. By them doing that I can't obtain employment no where else because of it.
