Paid Avast premium - No premium functions

Hello,

yesterday I paid for Premium Avast Antivirus (Order #802351823439).
I received a confirmation e-mail with Activation key.
Yet as I started the program a message comes up saying that the payment didn’t go through and the premium functions are stopped.
There’s a button “Renewal options”, but it.s not working.

how can I get my Premium functions???

If you’re payment didn’t go through, you need to pay for it.
If it has gone through, contact sales and explain the problem.
