engine mount and heater checked

I took my car in to get the engine mount fixed that I knew was broken because of my father and brother. I do not live at home so I took it in to MAAS Brothers in Portage, Ohio to get it fixed. I told them what had to be fixed and the heat needs to be looked at because its blowing cold air. I got it back few days later with a bill of over $400 dollars and he said the engine mount wasn't broken and that he didn't know what was wrong with the heat. The engine was vibrating and making a loud noise like it did when I first took it in. He said its normal for that car to be so loud and vibrate. Next Christmas when I went home I had my father look at the heat and it took him 10 minutes to fix it. The wire connecting to the knob was broken. I was taken advantage of. And I knew it but what more could I have done then to question them and them giving me bullshit answers? This happened a while back and I left a review for it then too but it seems to be gone now so I will leave another one to warn people. I was trying to sell my car and found out for sure from a different mechanic that my engine mounts have been broken for all those years MAAS Brothers Enterprises Inc said it didn't need to be fixed. I love Kermits Restaurant but I just researched and found out its the same people from this shop that owns it. I think they figured I was another collage student was going to move away. Well I'm staying in BG and I will let everyone know about this incident. Small towns should be good to everyone not just the townies. I have become a townie but to think some people think they can get away with bullshit disappoints me. Thank you
