They called two days in a row and have not left a message and I have no plans on calling them back either.

yup, just got one from these guys. won't take a call from an 800 # and waste my minutes and no they didn't leave a message which is good cause i would call them back and yell at them

They called but didn't leave a message.  I did not pick up, and don't intend to.  ;-)

They will call but not leave a message.  Called back and it's promotional advertising calls (for Time Warner Cable subscribers).  Call back and tell them you don't want them to call.
