Rb button broken. How i can repair my controller?

hi everyone, I have a controller with the broken RB button. The controller is under warranty. I tried to contact support but it is not provided. Furthermore, the serial number is not found in the system. I don't know how to do it, who to contact
and how to repair my controller. I hope someone helps me. thanks.

You can request a call back from an agent.

If they cant get you sorted. Might look to see if the retailer you got it from can swap it out might be faster in the long run

Once the RB button was broken in one of my controls.

the button wont work anywhere, its a controller issue i cant find anything online about fixing it the only other controller i have is broken,the back left of the rb button will click in a tiny area but the rest of the rb wont click and feels stuck when i press it

So there is no way to repair a broken controller out of warranty, all I can do online is buy a replacement for $70...

How did other people mail in their controllers for repair?

You can try deleting the update:

a.Press the Guide button on your controller.

b.Go to settings and select System.

c.Select Storage.

d.Enter the following button sequence: LB , RB , X , LB , RB , X .

e.Select the option to roll back all system updates that are installed. The console will restart automatically and then download the updates again.

But if you still have the issue, repair is going the be needed
