Pisses me off

When you send me a really rude e-mail insisting that I call you at X time at X number and then when I dial X number it seems it's not in service.

Thank you for making me reorganize my schedule and wasting my time. How very thoughtful of you. Next time we'll be working around MY schedule because apparently you're not smart enough to remember 10 simple numbers. And yes, those 10 simple numbers would be to your own HOME phone number.

Yeesh.
