GLC63s Damaged Rear Bumper Cover (Upper), what's the replacement cost

see the red square
Any one had experience how those parts can be fixed/replaced and how much they cost? BTW I sourced this link but it didn't mention colour so I wonder if it is legit. My car is metallic grey with night package.
Thank you for your help.
