Raiju Ultimate M4 button broke while playing!?

Hello razer heads!

So the other day the m4 button on my ultimate broke while playing. I have never abused the controller, and you can see this is a design flaw. I just know this will happen again with M3 button and feel this is really bad quality for a controller priced at 300$ i have had the controller for about a year so the warranty is no more. Is there a place to get a new set of M3 and M4 buttons so i can open it and fix this myself? I have looked all over the internet without any luck.

Will upload pics later.
