Continued calls aren't going to do anything. If OP was traveling alone, so there's no possibility that the certs are under anoter record, the webform is the way to go.
If FL doesn't come through, OP has two choices: 1) forget about it and move on; or 2) sue. OP can also file a complaint with DOT and hope that others have done so too.
Remember, FL is now WN and WN is WN. So, expect less.
