Pay attention to your delivery time estimates. I am not Zappos, and I don't pretend to be. You may think your package is weeks overdue, but in reality it is not scheduled to get there that fast. Don't unleash the beast within at me when the package isn't even late yet.
Remember that Ebay sellers are regular people! Great, you asked where your package was. I explained about the shipping times and said I'd contact the post office. Why on earth would you email me less than 24 hours later asking for an update? And then file a complaint the day after that without giving any time to respond?
What. The. Heck. I swear, people can be so horrible sometimes...
