It's possible someone else entered your data by mistake, or you forgot. Check your bank statements. Anything there you don't know about?

I called for an administrator.

Thank you for your reply. Nothing on my bank statement which is why I am not that concerned, the card they used is also not mine neither is the name.

My email is very different to the name given so it is unlikely to be a mistake entered. I am concerned if they are using someone else's card without them knowing, sending the receipt to another email so that person might not realise.

Alternatively it could be a complete phishing exercise, but when I googled the email it came from I got no red flags and only mozilla links. It was mozilla@m.mozilla.org
