It sounds like you have been through a nightmare! I had the same thing happen. When we moved here I needed someone to put my machine back together properly because the movers had taken it apart when they took it out of it's antique cabinet. I didn't know anyone in town so I took it to the local Singer dealer and he didn't know how to do it, although he said he did. I called and called for months until DH got tired of my complaining and went to get it. I ended up taking it to the Singer dealer out of town a ways but that old guy knew the machine and did a great job. It sewed just like it had for years previously. After that other people recommended the old guy out of town. He is no longer but the machine is doing great. Now that I have a Bernina I would never take it anywhere but to the Bernina shop that other's recommend, even if it was out of town. I've learned my lesson!
