Text messages at 1am

STOP SENDING ME TEXT MESSAGES ALERTING ME THAT I AM OUT OF DATA AT 1:10AM WHEN I AM ATTEMPTING TO SLEEP... I CANNOT OPT OUT OF THIS *******... THEN I RECEIVE MESSAGES ON MY OTHER PREPAID CELL AT 6AM ONCE I HAVE JUST SWITCHED ON MY CELL... NOT LOGGED INTO THE NET! THEN WHEN I DO LOGGIN AND RECEIVE A TEXT MESSAGE STATING THAT I HAVE BEEN PAYING R2 PER 1MB - THESE COSTS WERE SUPPOSED TO BE LOWERED MID OCTOBER FOR PREPAID CUSTOMERS... CHECK NEWS24 AND ENCA.. WAS THIS A LIE AS I HAVE THE TEXT MESSAGES TO PROVE THAT IT WAS ALL A LIE... SO ALL THESE MESSAGES I HAVE RECEIVED ASKING HOW LIKELY I WOULD BE TO RECOMMEND VODACOM TO FAMILY OR FRIENDS -WOULD BE ZERO!
