Ok ok, I'll participate,
That feel when a company decides to "refund" a purchase you didn't want with...the product you didn't want.
Long story short, I bought something that it turns out I didn't need and when I requested a refund, they just sent me another one of those products. I'm not complaining too much, though, as I could always use more.
Oh and another one:
That feel when no one gives a fuck. So stop.
