They won't return my emails, they won't answer the phone and everytime I go by their house they are not home. Finally in May, Shanti Kondolay called and said they would pay me if I signed a document saying I wouldn't make parts for anyone else. I told her I couldn't do that. She also asked for drawings and files that they had never paid for. I told her this isn't acceptable, you have the product, you need to pay me. She then told me she would call me tomorrow. That was the last time I had any contact with them and again they won't return my emails or messages or even answer the phone.
