Received a call at 1:30 Monday Morning. Answered it to hear one beep and then nothing. Called the number back and received a messaged saying i wasn't authorized to call from my number and was offered voice mail. I too thought something was wrong at that time of night. Very frustrating!
I also received a call at 2AM and woke up with the fast heartbeat that happens when you get startled. Called the next day and was told to leave a message. BOY, DID I LEAVE A MESSAGE!!!! Will take my phone off the hook from now on.
