They left a message but it was unlistenable - like a darth vader voice but too slow and distorted to be able to hear the message (like they had a pre-recorded message to leave and the tape is messed up). So I have no idea who it as who was calling.
WTH- the last couple of people who wrote about receiving a call from this number explained exactly how the message left on my machine sounded. It was creepy as hell. Of course, tried to call back but every time, there is a busy signal. I am guessing this is some sort of telemarketing scheme from people who have nothing better to do with their life.
