This guy was calling about advertising for our dental office. Gave the doctor the message, obviously he didn't call the company back. The guy from this phone number called back again the next day and said that it was very rude that the doctor never called back. I told him he probably wasn't interested and then he proceeded to be very rude and beligerant. When I asked for a supervisor he hung up on me. I called back and he asked if I worked for the FBI and then hung up again. Very strange and rude.
