Stupid Bank!!! Grr...

After school today, I finally got my hands on a money order from the bank and quickly slipped it in the envelope and posted it.
I was enjoying my evening untill I got a phone call from the bank cashier telling me that she had made a mistake on the money order and I would need to come back and get another one. Very annoyed, I explained my situation and she barely registered how important the situation was making me even more angry. Now I have to email PMUS and sort the whole thing out.
Seriously considering changing my bank because my current one are always f*%king up!
This may seem like something small to you but I am quite annoyed.
