The highest pressure sales tactics, cold calling everybody in the company they can find on LinkedIn / website / data broker lists. Started calling our board of directors at home and their day jobs asking why we weren’t returning messages. Verkada can burn in hell.

Oracle. We weren’t even a customer. We just had an ip space with a bunch of customers on it. Yhey tried to claim we needed to pay for all their virtualbox downloads since we weren’t a home isp.
