Trying to get my account disassociated issues

I have a personal account and am currently using a free license. 

At some point in the past, my account got associated with a company that I was doing some work for.   They had a trial of a license at that point apparently.

The problem I am running into is that I can't disassociate my account from the Company from my end..   I contacted them to do so, but since they were on a trial license that expired, they no longer have access to User Management to disassociate me.

How do I fix this?
