Xbox is broken

My Xbox 360 has been broken for several weeks. When we tried to print a label to ship it there was an error with the system and we couldn't get one to print. Mom called the company but they didn't help much. Later it worked but there was something wrong with the label, so we would have had to pay 15$ to ship it. Mom decided that she wasn't going to pay when Microsoft had already messed up previously. She called Microsoft again, and once again they were unhelpful. At this point my mom lost her patience and asked the woman on the other line if she would like " to hear her smash the Xbox with a sledgehammer" and threatened to put a sign on her lawn reporting how poor Xbox service was. I asked her if being shortchanged 15$ was really worth the anger she had worked up. She said that it wasn't the 15$ but "a matter of principle" I wanted to ask her how destroying something worth 250$ that had given me countless hours of enjoyment, to get back at someone who probably couldn't care less, because they took up a lot of her time and shortchanged her 15$ was principled. But I didn't. When she's angry trying to reason with my mother is like trying to give a back rub to a porcupine.
