So I got an email saying that Grime Fighter would renew in 30 days, about 30 days ago. I didn't want a new subscription, so I followed the link (avast.com/find-order), entered the given order ID and password, and manually cancelled the subscription.
Despite this, it still renewed my subscription.
I want a refund. The order number that I cancelled was 15794792642. For whatever reason, whenever the email kept sending me notices that it would auto-renew after 15 days (despite me cancelling it upon seeing the 30 day notice) it gave me a new order number and a new password each time. The email telling me that it was renewed successfully had an order number, but no password.
I don't know what's going on, but it's annoying.
