MBD HARRASING THE WRONG PEOPLE AND NOT DOING ANYTHING ABOUT IT

I have taken a vodacom contract over a year ago and was allocated a number which previously belong to some CARY REDDY OR SOMETHING...i AM NOW TIRED OF TELLING THESE MBD HARRASMENT AGENTS THAT I AM NOT CARY REDDY AND THAT THIS NUMBER BELONGS TO ME SINCE LATE 2023. EVERY AGENT SAYS THEY WILL UPDATE THAT THIS NUMBER MUST BE CHANGED, THEN GUESS WHAT, A FEW DAYS LATER GUESS WHO CALLS...RIDICULOUS
