I called back the number and got a message. They say they are "Vehicle Service Direct". At the end of the message it says press 4 to be put on the internal do not call list.
This company calls me every single day, several times a day and hangs up when I pick up the phone or is silent. Once I said please remove me from your calling list they said ok and hung up. They still call several times a day and hang up when I answer the phone. Some one from that company needs to fire their incompetent reps for not doing their job.
