Vodacom account security abysmal.

My acct hacked because of ridiculously basic security questions. *****ulent upgrade of my contract was undertaken and an iPhone 15 pro max ordered. I had to personally phone the courier to cancel the delivery of a new phone to the hacker and now have to wait up to a month for resolution of the *****ulent upgrade! I duplicated the process that one would need to follow to upgrade *****ulently. Turns out you don’t even need to have access to the phone you are upgrading! You can do it off another number! Absurd!
