Retrieve landline vm messages from wireless?

Ok, thanks. I'm lost in here. I'm old and a newbie in here. Had better luck by using the * instead of #. Called At&t originally. My gosh what has happened to this company? After approximately 2 hours, could not get a correct answer from a rep or a supervisor! Got a few answers. Ended up all were wrong!! Now I just need to find out how to transfer my landline calls to my wireless from the wireless. At&t get it together so this doesn't have to be a hair pulling experience. A department that is fully trained, on all your features, would be nice and more profressional than the mumbo jumbo answers your giving to customers to get them off the phone!
