Oh yes. I bought a vehicle with AudiCare. The dealership tried putting it on the invoice as "Other Aftermarket". When I went to use AudiCare the vehicle wasn't registered and they said that that fee was for a "second key" (even though it was 2-3 times the cost of a replacement key, and matched to the dollar the amount for AudiCare). Even when I showed them a photo of their breakdown pre-invoice that said, "AudiCare $xxx" and I'd signed it next to the sales managers signature they still balked at honoring it until I made enough of a loud fuss in their showroom in front of other customers.
