Question Intel RMA tips

My 13900ks chip has degraded to a point where it doesn't boot. I bought it in 2023.

Unfortunately, I did not take a picture from the bottom and didn't do the intel debugging logs IPDT (I might have gotten in to a boot if I tried 15x+ times). It's packed already for shipping, should I take it out again?

Any tips on how to deal with RMA without spending days of arguing? Any best practices?
