I have a problem with my wired Xbox 360 controller.

I have a refurbished wired Xbox 360 controller. There's a cable malfunction between the USB dongle and the "I-don't-know-what's-it-called" part, it's because I usually store my controller with the cable wrapped around it. Here's a link to a picture of the controller: https://db.tt/a4ri5kAB

Any solutions besides buying another one?
