Debiting Bank account after software deactivation and requests to delete account.

Avoid Avast at all costs. There is no way to opt out of future payments to them. Even if you uninstall their products and delete your account with them, they'll still try to debit your bank card. The only way to get any resolution is through their online chat, there are no contact details for anyone to address your concerns, they say no contact details exists for Avast ZA. Worst bunch of con artists I've ever come across!
