I thought there weren't any quilt police. Sounds like you found her as she sure made comments about your quilt--and fined (charged)you besides! If all of this was "wrong", it was wrong when she accepted the job and she should have said so before she started the quilting and just returned the top to you.
Advertising is the best reward for a job, whether it is well done or not! Don't libel yourself in what you say about your experience but other quilters should hear the facts and know to be wary of this person's service. Maybe all who hire quilters should take a picture before and after?!
