Not mine but this is actually what I did too.
I said I plan to charge back on my credit card. They threatened that if I did that, they can’t promise my account wouldnt be flagged.
I said “bet” and they removed the cancellation fee and cancelled the service.
Can I use Privacy.com outside the US?
Their support article says no, unfortunately https://support.privacy.com/hc/en-us/articles/360050917053-Can-I-use-Privacy-if-I-live-outside-the-US
I don’t think so. Canada does have similar services through some banks, IIRC.
