Hi everyone, I'd be grateful for any help/insight regarding this;

Around 3 weeks ago I signed up for a free account with Proton VPN. I was abroad and needed to send some E-Mails and you need to get permission from the company I work for if you're using Outlook abroad. Given it was the weekend I just thought i'd get a VPN and try to navigate the issue.
Approximately 2 weeks later, Proton have charged me £104.10.

I have

a) no idea how this computes as none of their packages seem to add up to that

b) I don't recall ever giving my bank details (But obviously I did..)

c) I've got no E-Mail receipt for this purchase, not even in junk mail!

d) I've sent an E-Mail to them using their contact form.... Nobody home..

Any help??
