Topic: Wii u gamepad left analog stick

Hey, so the problem I'm having is that my left analog just constantly goes left, I've bought a new analog and cleaned the area and still just goes left, I have tried the A, B, + and - to calibrate it, but it doesn't seem to work, on the odd occasion when it does just go left it won't let me move it left. So it's like all or nothing, can anyone help?

Thanks in advance
