TeamViewer is a disgusting, despicable company, and I feel very sorry for anyone who gets caught up in the licensing scam you people operate.
It's a deliberate trick, the way you don't send out reminder emails, spam customers with irrelevant emails and then make it impossible to cancel, except for via some sort of absurd ticketing system answered by incompotent robots.
I've been trying to cancel my acount for several months. I wish I'd looked at TrustPilot reviews before paying you **bleep** any money.
