It was just the email me thing, i filled it saying it was missing and got an email a bit after saying they handed my complaint to the respective team and that in 48 hours I should know the outcome.

Yes, It's perfectly fine to sign.

We shall await their reply.

What is MEB?

MEB = Manufacturer Empty Box.

I didn't sign anything, maybe I didn't explain myself right, but when you choose to contact them via email there's a small box to briefly describe your issue, thats what I filled.
