Since we're all being honest about our feelings on this thread, I will chime in on what Chihua5 just posted.
In her particular situation, I also would have called
Coach to notify them that I hadn't been charged. I'll admit that part of that reason would be that I'd assume that inevitably they'd realize their error and rightfully charge me anyway, and I'd like to know when I should expect the belated charge. Plus, I wouldn't want the rep that took my order to be reprimanded -- people make mistakes.
However, and this is a big HOWEVER... after my initial phone call to them I would NOT have called again! I'd feel that I did my part to notify them and that would relieve me of any guilt. So, if my initial phone call was ignored, fell through the cracks, went under their radar, was accidently not recorded because it was an employee's first day on the job, or any other one of the myriad of unacceptable excuses that I've experienced with retailers over the years when the ERROR WAS IN THEIR FAVOR AND AGAINST ME, I'd be fine with them neglecting to charge me. After my first attempt to be honest and ethical will be ignored (like it was with chihua5, plus they even laughed at her!), then it's ON THEM! My blood would have boiled if after my third phone call someone makes fun of me instead of thanking me for doing the right thing.
As we all say on here, "that's just me". I'm not judging anyone else's thoughts or intending to offend anyone.
