I am a professional sponsorship consultant, and because clients keep asking me about online fundraising tools, also a Wordpress site builder.

People makes mistakes. People get angry. People do stupid stuff. Umm..Stuff happens. So, what's important is how we work to fix things as best we can after they have been broken. Sounds to me like things fell apart because of a disagreement, and that the original issues were less significant than the disagreement itself.

If Pantheon was sponsoring one of my clients, I would now be focussed on finding a way forward even if I had to give away a few sponsorship assets. Based on the comments above, I don't consider a refund to have resolved the matter.

If I was sitting on the other side of the table representing a sponsor, I would be watching what happens next before recommending my client commit any partnership funds. This issue has bigger implications than this one deal.
