It makes it more clear to me.
In fact, the immigration officer contacted us prior to this refusal letter asking us to explain what happened during this offence (it was an opportunity to help them take a decision). We honestly replied what exactly happened, however our explanations were not satisfactory as "we did not provide enough evidence". And so we got a refusal. Our mistake was that we didn't gather enough evidence to explain the situation. We probably should have hired a lawyer right there...
Today I sent a letter that we are not appealing the decision...
