Took my 2006 polaris sportsmen in to get the 4x4 ...

Took my 2006 polaris sportsmen in to get the 4x4 looked at as it stopped working. Took it in and they told me i needed a new front diff. Over one month 1600 dollars later and they "fixed it" its been 3 years since , and i only use this 4 wheeler to plow snow. And we haven't gotten any snow in the last 4 years here so yea i havent used it much at all. Got it out last week, again the 4x4 would not work so i took it to another shop. And heres what the new shop literally told me. " we are not sure who put this front diff in but they got all the wiring wrong. Looks like a quick and hurry half ass job to us. " so now i have to pay 480 bucks to re-fix the incorrectly installed front diff that freedom cycles put in that took them 43 days and over charged me 1600.00 to screw me over basically. Also they incorrectly installed a rear bearing on another sportsmen of mine. Paid 450, 5 months later the same bearing is making a poping sound, called freedom to ask them to fix they're screw up, they just wanted more of my hard earned money. "There is nothing i can do for you" i think was the quote i got . Ive delt with this place for over 5 years and im done. They dont know what they are doing. I wouldnt let any of them change a tire for me.
