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 started to get continuous calls from this number after my Hyundai was serviced. I called the number back and the recorded message said it was Hyundai doing a survey on my recent service and they would call me back; they indicated no way to contact them. I called Hyundai Customer Service at 1-800-633-5151 to complain. The rep told me that Hyundai does not do telephone follow-up surveys, they only use mailings or email. They could find no record of this number and she said they don't contract with outside companys for surveys. They opened up a file and are going to investigate and I'll call in a couple of weeks to follow-up. I would encourage all to call Hyundai customer service directly to complain.
They called again today but this time I was here to answer. After asking 3 times, she finally admitted that she worked for a market research company called Synovate, "calling about your recent service on behalf of Hyundai". www.Synovate.com, these calls coming form their L A area office apparently. I told her I didn't appreciate them calling and hanging up multiple times, day after day. I demanded she take me off their call list and never call my number again. I also called Synovate's customer service line at 866-320-4607, and they have an automated prompt so your number can be added to their company Do Not Call list. From what I read, as a "market research firm" they are NOT bound to follow the Federal Do Not Call list so they CAN call you even if your number is on the Federal DNC list! Another DNC list joke at our expense. I guess the best recourse at this point is to call Synovate's 866 number to get added to their do not call list, and call the Hyundai Customer Service number to complain.
I made a follow-up call to Hyundai and this time they told me that they do indeed contract with companies such as Synovate to do phone surveys. I told them that Synovates constant calling and call hang-ups are tarnishing Hyundais reputation.
I did find out that Hyundai has an "opt-out" so that you can opt out of phone calls, emails, or mail from Hyundai. Call them at 800-633-5151 and "opt-out".
I called Synovate at 866-320-4607 and "opted-out" from them calling me, too.
