Very unprofessional staff. I called Steinberg diagnostic with a few questions I had regarding a phone call I received from them; Sandy R. (If that is even her real name, she refused to give me her last name) answered the phone and she was rude, unprofessional, and seemed annoyed from the beginning. She was unhelpful and didn't answer any of my questions and basically said there was nothing she could do for me and to ask someone else, yet she hadn't even tried to find an answer. I asked her who I should ask and talk to and she said she didn't know. She obviously knows nothing about the company and shouldn't be an employee. You would think that since she doesn't have any knowledge about the company that she would at least be nice or professional. DO NOT come here , you will leave feeling uncomfortable because the lack of knowledge and professionalism.
