Help for a Puzzle

Hello everyone I hope you’re all doing well with the collab ongoing.

Anyway I decided to take a little break from the game and decided to do a puzzle that I purchased roughly 2 years ago (in Europe while watching the final at a convention center that was organized by Com2us).

After nearly two months I am nearly finished but I realize I missed a piece to complete. I wanted to frame it but can’t do it before I have all pieces.

Do you guys have any solutions ? Do you think I can contact Com2us directly and see if they help me with the piece I am missing? I don’t mind paying as long as I get the piece I am missing.

Thank you for your help and may the god of rng bless you with a LD nat 5
