My problem is that I am applying for insurance on a new vehicle

My problem is that I am applying for insurance on a new vehicle. I was given a quote but simultaneously told that in one month from now there will be an annual increase on my insurance premium because it's my yearly anniversary with miway. Note that this is a complete new policy on a new car. if I take the offer from First for woman there will only be an increase in a year from now. This action by Miway should be reported as *********. How can they effect an increase on a new quote after 30 days (April) just because I am an existing client. It seems like a kick in the groin to an existing client. Regards Gerdi Engelbrecht ***
