I have bought AVAST INTERNET SECURITY and Avast cant see my paiment ! I have billing from my account proving I have paid for the product, they dont have any email adress for customers, nor any phone number for clients from Poland. When I try to call the british customer phone noone answears the phone. I want my money back or I want my antivirus to work, because I’ ve paid for it and this is very unproffesional that I have paid for the product and they don’t see it. I have billing, if AVAST want the prove. Pleas contact me on my e-mail to solve this problem.

Good luck! 
Don’t worry they will straighten things out. Keep in mind it’s the weekend so things might be a bit slower.
