I recalled this number after they called me at 0438 AM to verify the message on the other end since I was pretty out of it at that time, understandably so...Here is what the message actually  said "The text mail subscriber you are trying to reach is unavailable, please leave your message after the tone".....these are no doubt scammers and this is a spoofed number without question...I say this after researching the Text Mail service provider...call could be from anywhere in the world, not exclusively Austin as this service allows you to "pick" your phone number....I have difficulty sleeping and it becomes impossible to go back to sleep when someone wakes me.  I do not have the privilege of turning my phone off during certain hours as I have friends and family with acute medical conditions and at any given time may need to contact me.....Inconsiderate lot of folks these scammers are, greedy prigs who seek to seperate you from your cash....may their Karma overrun their dogma with a herd of angry elephants who decide that trampling was never so much fun and go back for a second and third run over them!
