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.
I recently traded in and purchased another Hyundai and have received calls from this number as well. I don't answer. If this is a Hyundai survey and they want you to call back, why aren't they using a toll free number?
I recently took my car in for a repair and they are wanting you to take a survey to determine how you felt about your recent dealings with Hyundai. It is annoying seems like they should just mail out the survey. I also received calls from the same number when i bought my hyundai, i never answer eventually they quit calling.
