Repair Cost(Hinges broke plastic)

The hinges on my MSI GP63 Leopard where too tight, therefore broke my laptop as you can see above.

My laptop itself is working fine, but I am very worried it will cause serious issues in the near future.

My warranty is expired.

What steps should I take next?

Learn and repair myself?

Send ticket to MSI? (I heard they have very bad customer service)

Or Take it to a repair shop?

I live in London, so if the option would be repair shop, which one would you recommend?

Thank you for taking the time to read this, hope to hear back soon,

Samuel.
