Arrigo Dodge Chrysler Jeep Sawgrass review: deduction from 1410.00 dollars

They deducted $984.09 from the money that I paid for 7=seventy coverage for full coverage for repairs on 2009 dodge truck which I purchased in january of 2009. I went down and wanted my money back totaling 1410.00 dollars for extended coverage. They agreed that this money was money was mine but when I received the check in the mail I was really surprized because it was only for 984.09 dollars. When I left from this dealership I was under the understanding that I was to get the full amount of 1410.00 dollars. I signed a form for acceptence of this amount 1410.00 dollars and left the place and went home. I get this check in the mail and was I surprized.. I tried to call got the automated phone system and I could only leave a call me back message. Twice and have not received a callback from no one there. I would like to know your opinion on this or an explanation of why thesr people deducted almost 500.00 dollars short. Hope to hear from you soon, Edwin J. Deremer
