Questions to include in a customer survey?

I have down demographic questions (sex, age, income, etc.)
Now I need qualitative and customer related questions. The company we're working with is an insurance agency and they are looking for strategies to increase spending (which has actually gone up significantly in the past six months) and to increase customer loyalty. What can we ask their customers to help us increase customer loyalty?
