Bad service and they are *****s!!!

I have purchased 5Gb on the vodacom application where I'm supposed to get an extra 5GB which I never received!! I've called twice first operator was useless! ! Second operator was helpful he clearly state that my extra 5gb was never allocated to my NUMBER than a technician called and was even more useless TELLING ME BULL**** THAT I USED THE 5GB AND THAT I SOULD CALL THE PHONE PROVIDER! ! WHEN I PURCHASED THE 5GB I ONLY USED MY BANKING APP AND WHEN I WAS DONE I SWITCHED MY DATA OFG SO HOW THE **** DID I USE 5GB????? MY PHONE DATA USAGE CLEARLY SHOWS FROM 25 AUG UNTIL NOW I HAVEN'T EVEN USE 1GB OF DATA AND THIS 5GB I UPLOADED WHICH SHOULD BE 10 I UPLOADED ON THE 28 TH OF AUGUST SO HOW THE ****???
