I never got an email at all in the first place. It wasn't a problem with downloading it, I just needed to activate it. The first thing I did was try to resend the license, and got an email that said I never bought it. I submitted a ticket that got no response after about a week of waiting.
I called the support line to ask why and they said I never bought anything, but my bank statement says otherwise. Even if I did make a mistake with my email (chome auto-filled it so i don't see how), I also gave them my name, phone number, and the order reference number they gave me with my online receipt. That should have been more than enough info to retrieve my information. I had enough of their "help" so I asked for a refund. They said I never bought anything so they couldn't refund anything. They went on to say the only way they could help me further was if I bought something else. I hung up and disputed the charge through paypal.
The only reason I wanted to contact avast at that point was to let them know how unsatisfied I was. All I wanted was the product I paid for, which is too much to ask I guess. All I want now is my money back and for people to know what happened to me so it doesn't happen to them too.
