Am I wrong?

I let my parents barrow my 100 dollars that i got from working and from my grandma. My mom said that if there were no new bills (we dont have much money) that i could get my money back when taxes come in. Well, taxes came in and no new bills. I wanted to buy an exersise machine my dad fought with me all the way. Now i finally got it and he wont take me to get it. (Only his veichile will fit it) He had the day off so that is not the reason. He just wont. Am i wrong to be angry? (sorry for the typos im typing in the dark)
