I purchased my CRV from Bill page Honda in 2014. I received five free oil changes and a $50 on a "customer rewards card." for the last two years, the only maintenance I needed was an oil change, so I used 2 of the free oil changes I got. Two days ago, I took my car for maintenance which included engine oil change, tire rotation, gear box oil change, and alignment. The total amount due was around $325. When I tried to use the $50 on my customer rewards card, the cashier told me that the customer awards program was canceled last year and it no longer exists. I asked to speak to a manager, and the manager repeated what the cashier said that the rewards program was canceled. I believe canceling the awards program without notifying the customers is a bad customer service. Bill Page Honda should have notified all of its customers and asked them to use their credits before the program cancellation date. In addition, the dealership should have continued to honor the credit on these customer rewards cards. Since the customer awards card says: "Treat this card like cash," the credit on these cards is money owed to the customers and does not belong to the dealership. I'm very disappointed in Bill Page Honda. I think this should be a good class action lawsuit. Let me know if you have had a similar experience with Bill Page Honda.
Thanks.
