only way your rate could change mid term is if you moved to a new place added removed a vechile, driver, or coverages. If your rate did increase your agent should be able to look of the policy and see what chagned if they can't figure it out they need to contact the Regional Office. They should be able to say why. If it did increase without any change being done they should honor the org. rate for the rest of the term. If it was a renewal issue. Your office should have called you to let you know your rate was going to increase and why.
Our ID card will show the current term info.
as for the adjuster you have a PM.
