I have been a customer since 2012; within that time frame I have purchased 3 vehicles to include 2 referrals which have purchased an additional 3 vehicles. My most recent purchase a month ago I must say was a nightmare and has made me question my future business with this dealership. Finance Contacted me a week after the purchase on a Wednesday and requested I go back to re-sign because the original contract was voided and the new contract was going from a 3.9% to a 5.9% interest rate (Which was quite a shocker since that was never mentioned during the negotiation/original term of agreement); may I add my credit was queried a total of (4) time throughout the month of November by Courtesy which is not good. The sad part was the Finance manager contacted me and informed me if I did not come in by the end of that week they will not be compensating me for my time/drive which right off the bat left me in disbelief. Once all was said and done I attempted multiple time to contact someone from management their in order to speak to them about this experience; after multiple call attempts and voicemails left, not one person from Courtesy Chevrolet has returned my call or attempted to follow up. I recently completed a survey from GM which was emailed to me which was rated very poorly. After a few days of completing that survey a Service Manager from Courtesy Chevrolet named Mike Dyer responded to my survey in order to contact them in regards to that matter which I emailed the email address provided and was returned as invalid. I have also attempted to contact my Sales Associate which I have had no luck in getting any sort of call back or response. After all this I have come to the conclusion that this dealership will only provide you that great Customer Service to get you to purchase however once they've received their money the customer service disappears.
