BILLING AND BAD SERVICE

I UPGRADED. I ASKED TO STOP MY SMS BUNDLE BUT EVERY MONTH I AM CHARGED FOR IT. I ASKED TO CANCEL THE INSURANCE ON MY DEVICE. MY REQUEST IS IGNORED. I SIGNED A CONTRACT TO PAY R131.58 MONTHLY FOR MY DEVICE. I GET CHARGED R307.02 MONTHLY. WHEN I WENT TO THE VODASHOP IN CENTURION MUNZHEDZI PHUMLA SIMPLY SAID MY CONTRACT WAS A MISTAKE. IF THE CONTRACT SAID R307.02 I WOULD NOT HAVE SIGNED IT. NOW I SIMPLY HAVE TO PAY IT AND THE ONLY ANSWER I GET WAS THAT THE ORIGINAL QUOTE WAS A MISTAKE. MUNZHEDI PHUMLA SPENT THE TIME I WAS WAITING TO RESOLVE THE QUERY FLIRTING ON THE PHONE WITH CUSTOMER CARE. WHEN I GOT UPSET SHE LAUGHED IN MY FACE AND LAUGHED WITH A COLLEAGUE! MY INITIAL CONTRACT THAT I SIGNED FOR FOR R699 IS NOW COSTING ME A WHOPPING R1700 PER MONTH. NOTHING ON MY STATEMENT AGREES WITH THE CONTRACT I SIGNED.
