I believe the call you are refering to is a survey, I actually answered the phone, they explained they were a survey from a shop I recently had my car serviced at, I could not do the survey at that time so they told me they would follow up later, since then they have been calling me almost everyday, one of these days I will take the time to do their survey so they stop calling me.
I got a call last night from this number but, like all the rest, they didn't leave a message. I'm different then a lot of the rest of the people. I have not ever rented a car nor have I had a car in a repair shop.
