wow!!!! That is nasty!! I'm so sorry you are going through this, and I'm glad your mom is also on your side so they have to be accountable to more people than just you. And, I'm glad they found a way to put the $200 back. At least that's something.
I have to share with you something I did as a good deed that backfired on me, because we've all done it. As a result I'm a lot more cautious now which is kinda sad but I need to protect myself. I has befriended a man at my work and his wife and we did a few things together. Then one day the man came to me at work on a Friday and asked if he could sleep at our apt as his wife had changed the locks, emptied the bank account, and filed a restraining order on him. He had no money, did not have his visa (he was from another country) and was in a bad situation. I did not believe he was the type to abuse anyone either. So for a week he slept on our couch until he got paid again and had $ to find an apt.
Well, the wife accused me of having an affair with her dh! And threatening to kidnap her children, which is why the police showed up both at work and at my apt on a few calls before they got wise to her. She sent a dead bird to me in the mail, sent a photo of me with a gun pointed at my head (and I was pg at the time, terrified me so much) and several tearful apology letters in between these incidents. I finally got the police on my side and they threatened to charge her with mail fraud and such, and she finally left me alone. She was also apparently doing this to another family and spray painted their garage door or something and got herself arrested. I had no idea what kind of person she was until I did my good deed to give her dh a place to sleep. Wow.
I hope this all gets resolved soon and I would just steer clear of them from now on and just say goodbye to the remaining money.
