Hardware Wii Classic Controller Pro, analog stick gets stuck in one position

[SWATlozar]

So I got a third-party controller off Amazon for 15$. I know I cannot expect it to be like the Nintendo one, but this is unacceptable. The buttons and right analog work fine, better than I expected, but then comes the left analog stick. It gets stuck after I push it in the upper-right position and I have to pull it back manually. Other than that it works fine, but it really kills the fun when I have to play a game which requires a lot of precision. The problem sometimes changes. Sometimes it doesn't get stuck, but feels rather woobly. Sometimes it gets stuck in a different position, like the right or lower-right.

Firstly, yes, I know that third-party controllers suck and don't last long. But note that I got this controller yesterday. I don't want to mess with Amazon anymore, I don't even know if they accept refunds (tell me if they do) plus the first-party controllers cost a fortune.
Secondly, I searched through Google. All of the suggestions say that I need to either disassemble the controller or buy a new one. I'm not going to do either of those because, as I said, I got the controller yesterday and I'm not about to break it right away. Also, I'm not about to spend another 15$ on a controller that very likely would come in the same condition.

Any help fixing it without disassembling the controller is welcome.

Thanks in advance.

IIRC the original Classic Controller costs 20$.
It seems you got a defect controller, ask for a refund.

Okay, I'm gonna check if a refund is possible. I would like to know if there is a solution in the meanwhile. Thanks.
I forgot to mention I bought it through the italian Amazon. The original Classic Controller costs 35€ there. A little too expensive.

The issue still persist. Amazon won't give me a refund and I'm not getting a new controller after just two days.

The analog stick works completely fine, it just gets stuck in one position and I have to return it again. Also, it started making a not-loud-but-annoying squeek. Please help me. I just want to play some SNES RPGs.
