Hard call...

except the evidence isn't totally gone. You do have dated pictures here, online, which, believe it or not, counts as establishing a chain of evidence.

You don't have any physical proof of the prior arrangement, except reasonable expectation was established when you told us what you expected to happen here on the forum, which is also time-stamped.

Personally, I'd print a copy of this thread and mail it to myself, just in case I needed it later.
