What do I say about why I left my last job? (Boston)

They always ask why I left, and I freeze. I worked as a customer-service rep before this. I do not want to blame the company. Do they ask follow-ups?

I keep it to two sentences: the company cut my team, and here is what I am proud of and what I am looking for next.

Say it plainly and move on to what you can do. Interviewers usually move on if you do.
