This must be some sort of abuse. This is SO wrong. They call me SEVERAL times a day EVERY DAY and when I try to call them back, their phone rings once and then an automated voice comes on and says "good bye" and the call is instantly disconnected. I have blocked this number but my phone still rings once before blocking the call. THIS IS WRONG!!!
This number has called me so far twice every time I answer they don't speak and hang up. I tried calling back and it would just hang up except for the one time I heard a woman's voice then it quickly hung up and wouldn't do it again. I don't know how they got my number or why their calling but it's now a rejected call and won't bother me again too bad more phones don'T have this feature.
