Metro pcs for some reason deactivated my number after only a month(life happened and the bill didn’t get paid.) and I lost the number I’ve had for almost 5 years. WTH? I can’t get into any of my accounts gmail facecrack ect... how do I get my number back? With out it I really am at a stand still. That number is even connected to my job and life has been a real pain. I’ve called it and it’s not active with another customer as far as I can tell. What the h do I do?
