It's not complicated... I don't trust the judgement of someone that behaves this way. I have no idea what the contract said, or who is in the right. All I know is I'm not going to take the chance that they don't agree with the contract and now I'm litigating on Facebook....
If you pay him, you'll have no problems.
You were planning to pay, weren't you?
