fire you, he fired your daughter. Why didn't she call? He might have been willing to provide it to her. She doesn't seem to care enough to do the small amount of work a phone call takes. This could mean that she's lazy, doesn't think she really has a case,or that you are operating without her knowledge. I'm not sure what was said, but it had to be a little heated for him to ask three times if you were threatening him.
I'm not sure why you think it's a witch-hunt. He didn't just fire your daughter, he fired two other people. When times are tough and people are getting cut, only the best keep their jobs.
