Call this morning and had absolutely no resistance to receiving the $100. Had no wait time - a Customer Service Specialist picked up right away, and the individual was actually quite apologetic that the credit was not for more. She didn't try to sell me anything or minimize my option with a bunch of other, less attractive options first (tongue in cheek to the reports of UA CSRs offering FFC, ETC, then refund as a last resort!) United should take lessons!
