Just got a new phone from us cellular...it doesn't work!?

Yesterday I got the new Motorola electrify M from us cellular. It seemed to be working fine and I was really happy with it! But then I noticed that the phone didn't receive texts or calls! I can text people and they get the message, but when they text me back it says the message sent but I never get it on my phone! I can't receive calls, and when people call me it goes straight to voicemail and my phone never rings. When I try to call someone it says the call didn't connect. Other than this the phone works great! My dad got the same phone yesterday and his phone calls and texts... what's wrong with my phone? I checked and it has my correct phone number and everything. Lastly, the only recent call is a call to Oklahoma... I have never called Oklahoma! Help!

PS. Don't say go to the store or call because it closed already. Is there anything I can do to fix this right now?
