Vodacom bill doubled

Seems like with the lockdown going on everyone’s trying to make a quick buck. My Vodacom account has suddenly doubled this month. Which is kinda strange as I was out of the country for most of March using a different simcard. Also trying to get information out of the company is like pulling teeth. I’m also not the only one with this problem I know of a couple of other people who have suddenly noticed that there balances have doubled in the last month. Not happy at all.
