Help on an issue between two school clubs please?

Ok so here's what happened. Our club was raising money for a field trip and we ordered something online to sell at school. Another club coincidentally ordered the same thing to fundraise for their club as well. Even though they were ordered from different club advisors, the stupid company sent all the boxes to the other club because they umed it was for just one club, despite the two DIFFERENT people that ordered it. All the boxes were sent to the other club. When they saw they had more boxes than they had ordered, they didn't think much of it and sold almost all of them (including the boxes that were suppose to go to our club). Might I add that our club advisor's name was even on the boxes that belonged to us, but I guess they didn't see it. After a while, our club wondered what was the delay with our fundraising supplies and we discovered that it was sent to the wrong club. Now here's the issue, even though it was their mistake to sell boxes that were not theirs, they . . .
