I took the money to pay for my phone...?

Out of dads bank account without asking. My contract I pay but this time cause of spending so much in xmas I didn't have enough to pay for it...so one month went past I ***** pay it then this month now 89.10...I didn't know what to do as I don't get money til next week and they were gonna charge me 500 plus the 89.10....and then I really wudnt be able to pay it. So when my dad was out I took my dads card and paid it. I'm thinking I could wait and see if he notices as he may not with 89.10 or tell her and gave money.
