Phone rings but caller leaves no message.

one of those annoying calls. simply ignore it and move on.

Called and didn't leave a message. I called back and got a robot saying that I'd gotten a call from a marketing company, but didn't specify which one or why. Pressing "1" is supposed to take my number off their call list.

Called but did not leave a message. Called them back and got a recording that stated "your account is not authorized to make a call to this number."

Just call them back and tell them to go to hell
