Gallagher Customer Service interview questions

I applied for a Customer Service job. They wanted me for another job that I wasn't interested in doing. They didn't tell me that until we were part way through the interview. It was confusing because they were asking me what I liked to do best and I said Customer Service. I think they thought I was over qualified for that job and needed a Benefit Analyst. I could have done the job but I felt burned out after doing a similiar job for many years. The other job included both Customer Service and Benefit Analysis. I wrote thank you notes after the interview and followed up with them but they didn't return my calls or emails.
