Where can i have my xbox one controller repaired?

My xbox one controller has a loose connection and I don't know where to have it repaired.

If you do it yourself it is much cheaper and faster. There are enough instructions on the internet.

You can do it yourself and if it's broken too much you can look for a good used one on Ebay or something and if you want a new one, you can also find it on Amazon. Because mostly when the controller no longer works you can buy a new one right away

Because then it is no longer worth it
