Don't be fooled into thinking that the" increase in revenue"  ploy actually is a real reason to increase your premiums-if that is the case- then when your revenue goes down have they given you a reduced premium? Over the course of the last 3-4 years I would say that a lot of us have experienced less income- and as such those premiums should be coming down with each renewal year- If you document your income vs premiums charged and toss it back into the agents face- there just might be some reduction- try it and see how they justify those continued increases.
