Ok--firstly, that sucks. Secondly, how awkward. So, if you were to take Pete's suggestion..do they care in the end?--the course was advertised as the correct distance, and certified but paperwork stands in limbo. Guessing world records, no Boston qualifiers in the wings...You could call their bluff and publicly humiliate them in the circles that matter yada yada and you would not look the better for any of it. If that is their offer and the only way to get reimbursed by reasonable expectation, how about getting an agreement in writing with a late fee tacked on of appropriate penalty or the option to pay within 15 days without penalty? Was everything initially verbal or was there any sort of contract?
