Sleazy insurance agent

I have called my auto-insurance agent several times, trying to reduce my premium. Twice, he explained to me in length details that my “premium” was decided by the “market” and “the computer”, not by him. Disappointed, I switched to an online insurance company and cut my premium by 250 bucks.  After I informed him that I would terminate my current policy, he said that he would match my new premium and still provide the help as an agent.  His immediate change of attitude only confirmed my early suspicion that he did not act for my best interest at the first place.  This sleazy * of *.
