How can I get the charging port on my sounbox pro replaced?

The GND pin in the micro usb port for the charger is severed. I think it broke while I was struggling to plug it in. The port has been giving me issues for a few months now and I've been using a very fine blade to move the pins back in place to line up with the slot in the charger. Now I need to replace the port because this piece is missing. I’m not good with electronics; I definitely can't do this myself.
