I need some advice about my about my girlfriend?

Well she is "technically" my girlfriend, because she asked me out last week and I said yes. However, the phone number she gave me isn't her. So what's the dealio? Is she messing with me? She gave me two numbers, her home number and her cell. Her cell isn't the right number I keep getting someone named Becky and her home number is right, but she's never home and her freaking Dad won't tell her to call me back
