Unfair treatment

I purchased a vehicle at ford Aurinia .it was my second purchased from them.my second purchased things went south since I was helped by another sales man by the name of Andrew Broudey.i feel like my rights as a customer were violated.the day the were drawing my vehicle purchase agreement contract they include warranty from M-sure(bumper 2 plumber) on my contract without even discussed with me,meaning that policy included to my contract were sold to me incorrectly.i signed my vehicle purchase agreement contract electronically on their iPad does why I didn't notice.they split that warranty over 72 month on my vehicle installment.i notice that on my vehicle statement.i sent them email but since they benefitted from that insurance they no longer care.
