Vodacom forgetfulness

Bad Vodacom customer service -My phone goes missing along with my bank card and I spend a week trying to hustle a phone without the use of a card. Imagine how upset I am when I finally get one and go to Vodacom only to be told that I was never updated from a contract to prepaid and therefore cannot do a sim swap. This means no access to my online banking or job demands which I get sent on Whatsapp. Now I have to wait however long it takes, for someone to look and click a simple button they should have done months ago. Please can someone correct this quickly, I really need to have this fixed asap.
