Caller ID only said "Wireless Caller", so I let it go to my answering machine.
They hung up as soon as they heard the voicemail.
Ten minutes later, I called them back from my Skype phone.
A female voice just said Hello? w/o identifying herself.
I asked whose phone number this was because I wanted to know who called my home & didn't leave a mssg.
She said, "It's Purple Heart?" (with a questioning tone - as if she wasn't sure if I'd belive her).
I told her I didn't have anything for her at this time, thanked her, and hung up.
