They've been calling me every day for 2 weeks straight, no joke. They always call around 5-6pm and don't leave a message. I took my car (a Suzuki) in for service about 2 weeks ago so at least now I know who this is. Still not going to answer it though.
I called the number back. It was a survey for American Suzuki motors (I recently took my car to the dealership for recall work). The recording told me to expect a call back in a day or two or to expect a survey in the mail.
No harm, no foul.
Thanks for the post - I took my car to Suzuki a week ago too. So, I'll either answer the call if they call me back again or I'll fill out the form if they send me one in the mail.
