I think the email option may be best as it establishes a support ticket with your email. Give as much information that you can to help track down your payment and reissue the license if it has gone to an incorrect email address.
You don’t have to have the subscription email as such, just the wrong one you entered and they can try and track that and any other information, name, etc.
From that page select the “How can I cancel my Avast subscription?” option.
You should also be able to open your existing Account right click on the AvastUI icon bottom right of windows > Registration that should end up taking you to the same area given in the above information. This is essentially the same Avast Account used to logon to the forums.
I’m also experiencing this same issue and I can’t find the order number or any confirmation, the links provided did not workout for me and I can’t find the email address for avast support to contact them about it, I tried live chat but it didn’t workout well
Hi,
the order number isn’t that important either, and if you’re asked for it, just put “00000000” … (there were many topics mentioning this before the community was overhauled).
On the other hand, David says that e-mail is the best solution, but I generally recommend CHAT if it’s available when you make the request (if not, try again later)… It’s easier to interact with support in real time, and you can also send attachments as proof.
