Didn't receive an email after buying the Avast Premium

Hello, after I complete the transaction of Avast Premium, I didn’t receive an email because probably I wrote the wrong email number, but now how can I cancel the subscription if I don’t know the email and don’t have the Order ID.
Please help.

You could try:

  • Sales change order details wrong email address given, etc. - Submit a support ticket You could try this to see if sales can track down your order - *** alternative question/issue *** Submit a support ticket https://support.avast.com/en-ww/contact/sales_other_general#pc *** -
    Refunds, cancellations, billing, payment or license issues and click Next.
    I need help with a different subscription or billing issue.

Depending on your location you can Phone or Email - 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.

I don’t know why you would want to cancel the subscription if you/avast can identify it.

Edit: having checked the link it has been updated to either Phone (which may incur international charges), so chat may be the only option.
