How can I contact Avast?

I just purchased a licence for protection of my computer. By mistake my e-mail address was wrong. Now I can´t get my licence which I paid for, and I cant use the contact forms that Avast have to explain my problem, because you must fill in the Order ID - and I didn´t receive any because my e-mail address was wrong.
How can I contact Avast without using the ready made contact forms that Avast provides?

Hi agneta.landegren,

I fixed your email address and resent to the correct one the order confirmation email, including the activation code.

By the way, you purchased a license to Avast Cleanup. Was that the product you wanted to buy? You mention that you purchased protection for your computer, but Cleanup is for a different purpose.

4 minutes after posting and the wrong email has been corrected.
This could be a new record ;D

Keep up the good work moroni.
