I've received three calls today from this number. Glad I read everyone's comments! I just bought a KIA last weekend. So I guess I will answer the next time they call. It's annoying, though, that they don't leave a message.
i get a call from this number everyday all day and nobody on the other side of the call. i even got a call at 11pm and it ticks me off because i have to be up early for work the next day.
