Van Horn Hyundai of Fond du Lac Poor customer service. Treated poorly. Fond du Lac Wisconsin

When trying to get a better price on a vehicle, I was told by Robby Roehl, Sales Manager, in an e-mail that I needed to "compare apples to apples".  He had no idea what vehicle I was comparing their's to.  Also, he told me "...if this one is so well priced, why haven't you purchased it?".  Is that how you treat a customer?  I then sent an e-mail to Tim Goeckerman , General Manager, about how I was treated.  I did not receive a response.  I also sent a follow-up e-mail to Robby Roehl and to Zach Jaschob, Product Specialist.  Neither replied.  I then found out the vehicle was sold.  I was not informed.
