How long should I wait for a response on a ticket?

It’s been seventeen days since I reported a ticket in which I had an issue with getting the wrong version of Avast SecureLine VPN. Since I don’t want to have to chargeback on Paypal, but only have so long to be able to do that, is there any guideline to how long I should wait?
Does Avast have a phone number I can call regarding issue with sales? The tech support numbers seem to only help with issues with the product itself. I feel cheated of ~$100 at the moment.
Ticket number is #116937.

Reported to Moroni, wait for his reply.

How long should I wait?

As the weekend is over, he should be around today.

Hi 721721,

I changed your license to the correct product (according to the content of your ticket).
