Verification is an issue but if places do pay and they can't decrypt the victim is likely to talk about it. Also for this reason, like others have said, the ransomware tools have trial decrypts built in or the ability to generate a program/key that decrypt some of the files so that the victims can see that the attackers have the ability to decrypt some of their files. That requires zero trust and is more difficult than just having a single key that encrypts or decrypts everything.
