Not received purchased confirmation email

I upgrade from avast free. But after I paid the amount through debit card I am stuck at the “You will be redirected to Merchant Website within 5 to 10 seconds…”

I have not received any e-mail from avast. How much time does it take.

But I did received a message from my bank that the transaction was complete.

Whats the problem, I bought the premier version.
