Worst customer service from Vodacom

I have logged a complaint on this platform and a representative from Vodacom named Magdalene Telis called and promised to assist me, she was supposed to do a follow up yesterday and she never called , she provided me with her email address but she’s not replying to my email . Why does Vodacom have *********** staff , even when you log a complaint there is no resolution. Can someone competent , who will be able to see my complaint through contact me and assist . Please refer to my previous complaint regarding cancelling a contract for a router that never worked .
