I received call on my cell phone from this # when I returned the call from a land line it was from a vehicle warranty company.

Seems like i get a call every weekday lately with the caller not leaving a message  .. some calls with area codes, & some without area codes... got a call listed on caller ID today from,   780-3266 dialed that number back and recordings from AT*T says .." if you'd like to make a call hang up & try again" ... i did .. guess what it said ?? AT*T says .." if you'd like to make a call hang up & try again". How did a call get placed to my phone yet return call does not ? why does the caller not leave a message ? & some of the messages are for people that do not reside on this property. wondering if that *67 option works the way AT&T said it would work
