They've been calling my cell phone every day and sometimes twice a day all week (July 22, 23,24,25,26, 2013). I decline the call every time, but so far it isn't stopping them.
There's a short mechanical sound, and then NOTHING. Frustrating, because this number calls at least once a day (sometimes twice). Leaves a blank voicemail message too.
They've called me twice in the last two days but I didn't answer.
Called the number back and there's an automated message saying they may have been calling on behalf of an automotive dealer (Hyundai in my case) to remind me of upcoming service or to ask about my experience. You can leave a message after the beep with your number to be added to their do not call list so that's what I did! :)
