My Parents reduced my Allowance?!?

Last week, I was getting 150 dollars per week for making my bed, dusting my room and taking out the garbage and picking up after myself! This week, they cut it down to $125 and I am PISSED! Like WTF I NEED the money so I can buy another laptop and another 56 inch TV for my room! And I'm used to getting whatever I want because my parents ALWAYS do but they didn't this time so im about to cry because i dont feel special enough!!! I punched 2 holes in my wall because I was so angry! What should I do to convice my parents to raise my allowance to 150 dollars per week without doing chores, because i HATE doing work!
