They said that I needed to pay $43 for a bill that they could not explain after I had already paid them for a $42 bill the month before. A few days later I got another bill for $73. I paid the $73. They sent me a check for $26 because they where going to cancel my policy. When I called my agent he told me that I could keep my coverage by paying $42 today by credit card, so I did. My agent told me that my insurance had been canceled one day after I paid. The agent called mercury and they said that I should be getting a check from them any day for the cancellation. When I told my agent that I had not received it, he checked with Mercury and they said that they would not be sending me the check, but that they would be applying it to the $43 that they claim I owe them.
