What Happened To My Service?

I've had service through Cricket since February of this year. A few months ago, my mother asked me if she could add my phone line to her family plan so it would give all of us a lower monthly payment. (Me, my mom, my brother, and my boyfriend) I agreed to the switch, fast forward to today, my mother and I had a falling out, and even though I pay for my own phone line, she was able to suspend/cancel/disconnect my service because she's the account holder. My question is what happened to my phone number and how can I reactivate/restart my service?
