I talked to Schwab this morning and their Corporate Division said there was nothing they can do as Ameritrade is in control until your account is absorbed into their system. They said to file a written complaint if this isn't resolved to Ameritrade by Certified mail. You can also file a complaint to FIRNA. The governing body over all brokerage firms. A simple form to file explaining the illegal sale of your shares without your permission. https://www.finra.org/investors/need-help/file-a-complaint
