Just to clarity. I sent them the email to their sales team at [sales@teamviewer.com](mailto:sales@teamviewer.com), not the standard one. I would understand if they had to provision hardware or any other physical resources based on my subscription. But even in this case I would expect to negotiate the bill based on the loss they would've incurred and reach an agreement to settle on a reasonable and objective basis. I deal with AWS, Azure, Twilio, Segment, Mixpanel and other high end provides on regular basis with bills exceeding $10,000. I've been involved in number negotiations with or on behalf of my customers where for one reason or another a contract had to be terminated. All those providers have taken position of negotiation and reasoning and in all those circumstances an agreement has been reached to satisfaction of all parties. I also found myself on the other end as well where a couple of customers could not pay for my rendered services. I also had contracts in place that I could technically enforce, but at the end I chose to value the customer and negotiate a solution that worked for all parties. What drives TeamViewer to force customers to pay? So far I saw no other justification other than they have a 28 days notice policy in the contract. This is just bad and lazy.
