I didn't receive the activation code

I’ve bought avast VPN but I didn’t receive the activation code

Did you buy from Avast directly or from a reseller…?

Directly, on avast vpn’s app, when the trials days expired, i just bought by credit card.

It asks “order ID” and I didn’t received this on my e-mail, its about this all this time.

If you don’t have an order # use 00000000 then explain your problem.
