1) we didnt need to state that because we already stated that it could be "no later then the 7th"
2) it wasnt in our best interest to cancel the cf then. They forced us to offer an EOA CF but we were under no obligation to point out or fix their mistake when they took a CF on the 8th despite it being clearly stated that our EOA CF could be accepted no later then 7th
Why didnt they follow up to confirm that it was an EOA CF after they missed the dead line? they could have renegotiated right then and we would have had no choice but to agree to new terms? They got greedy and missed the deadline because they wanted to get that last hit in, then didnt even bother to fix diplo. It's not a complicated situation, they burned us but messed up their diplo and didnt fix it. It is not our job to help fix the bad diplo of our enemies.
