I just bought a Hyundai and was told by the dealer to expect a call about th service I received. Probably the best way to handle it would be just to answer once and ask that they don't call back. Most reputable companies will accept that.
Calling to ask me about the service I received a few days ago at a Hyundai dealership. They only asked two questions, "Do you mind taking the survey?" and "How would you rate your service on a scale of 1 to 10". Took less than three minutes to complete.
It's a company that does customer satisfaction surveys for Hyundai. There is usually a note on your receipt letting you know they will be calling. They also send me an email.
