Unmandated Debit Order on my account, with no products linked to my name and no simple options to resolve.

Vodacom deducted R570 from my account this morning, and when I checked, it was linked to a debit order that I didn't authorise. I also checked my app, to see if there's a new account against my Vodacom number, and nothing is linked to my number.

I tried phoning the support line, because my "Self-help" options don't include "Please check why there's a unmandated debit order against my account," but getting in touch with an actual person, under an "Accounts option" is also not available.

Considering the absolute nightmare it is when going to a branch to resolve something like this, and writing off 1-2 hours of your day for something that isn't your mistake, I'm just popping this here in the hopes that someone at Vodacom cares enough to investigate why they ****** me.
