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.
Received a call from this number. Last time I took my Hyundai for an oil change the calls would not stop. My phone is a business cell phone and the company I work for frowns on unnecessary phone calls
