I am willing to lose the 10K miles on the first ticket and the first $75 fee rather than continuing to deal with this anymore.
Luckily I only have about 100K miles with united now and I think I will quickly use them up and never deal with united again. I like flying united as long as nothing goes wrong or I need to make changes but if you do, then I don't think I have ever, I mean ever, dealt with a company with worse customer service.
