Yep. Plenty of times. Both in RL at my last profession, and the online.
At some point I just do not want their business. If they contact me with a legitimate problem, I will try and help them fix it. If they constantly cut me off, do not follow things step by step, and just want to bitch (yes, some people just want to vent, and much like your wife there is nothing you are EVER going to do that will be good enough to solve it). I am not going to sit around and
a) listen to it, or take the abuse until they feel better. You have a health insurance card. Flip it over. The number for mental services is there.
b) take it in the ass for their $14.95/29.95 or whatever the dollar amount is. At some point they get their refund, banned from everything I own so they can never sign up again. In the RL I would put big PERM notes on their account they were a mental asshole, and transfer them to corporate security when they called in. Then I'd check back on their account in a few weeks and laugh my ass off on the additional notes.
