We were on 30 days trial. The trial was about to expire but things didn't work correctly. Tableaus aggressive onboarding team made me sign for a one-year contract anyway. They promised to support us until everything works. But that did not happen. So I talked to them. Someone seemed to understand and said, he'd cancel the invoice and give us another trial and hopes, thins will work. After a few months, it worked indeed. So we purchased again. But: we never got a license even we already paid. Statement: the old invoice needs to be paid. So although we have a written confirmation, that the invoice is cancelled, tableau didn't cancel and now we have no money and no license. Very sad company. The product might be great but the philosophy horrible.
