Bought a used truck from them 3 months ago and aft...

Bought a used truck from them 3 months ago and after a terrible sales experience I'm still dealing with the service department in getting something fixed that was part of the sales agreement. The truck has been there 4 diff times, they actually have it now and for the last week, when they told me it would take one day. On a good note the finance guy was great as he actually made the sale, everyone else I've encountered has been completely unprofessional.
