OnTrac Customer Service interview questions

This was a complete waste of time interview. I put in my resume for customer service position and was called in almost immediately (which should have tipped my off). Once I got there and actually spoke with the operations manager and he told me what the position actually was I realized I was duped into coming in and wasting two hours of my day. This interview was for a dispatch individual which I am overqualified for. He had the nerve to offer me 25,000 - 30,000 dollars. I felt extremely offended by the offer. I understand that that is what they want to offer a person, but do not lie about what the position is.
