I would ask the RE who performed your latest HSG what the clamp means. It is highly doubtful he will outright say this other doc performed it wrong/lied. But he can tell you what the clamp means.
Then it's up to you to talk to a lawyer or not if you want to persue it. But note, him verbally telling you what was up and what is written in the medical records can kill the case. If they don't match, you don't have anyone to vouch what he verbally told you unless there was a witness. I'm sorry you had to find out this way.
You only need 1 tube/active ovary to have a child. But also, there are still options for donor eggs or your own with IVF. If you're uterus is fine, that is what counts. My friend has a naturally blocked tube and she is doing IVF.
