Walser Honda

On August 24, 2016 I sold my car to Darren S. at Walser Honda Burnsville. I did it through Kelly Bluebook. The price quoted by KBB was fair and accepted by Walser Honda. So I took my car in they drove it and agree to purchase it. To a bit of a disappointment Darren told me it would take about 7 business days for me to get my payment. Today is day 14, no check and for the last week when I contact Darren to get a status on my payment. No return calls or emails. At this point I have nothing, no car, no check, just a piece of paper that says they agree to purchase my car. This is absolutely the worst experience I have ever had from any car dealership. They should be embarrassed at they level of professionalism.
