The thing about ransomware is that if paying the ransom does not actually result in decrypted files no one will ever pay a ransom again.
Many of your victims won't be able to say anything even if the files aren't decrypted -- this case is a good example, since the company in question couldn't admit publicly that they were paying ransoms.
A little searching shows that scams (beyond the base "pay to decrypt") are very common. You're dealing with criminals. If you pay a ransom, they now know that you have money that you're willing to pay, and they're going to do whatever they can to get more of it.
