Samsung galaxy s3 advice please.

[Arouny]

I took my Samsung galaxy S3 screen to be fixed and they guy told me he needs to change the screen but it will leave a mark on the top side of the phone. I accepted for the screen to be changed and he charged ?100 for it but when I got my phone back I realised the mark was bigger than he made it sound like and it now makes the phone look ugly as the phone is peddle blue with a black mark on the top side of the phone.

Is there anyway I could get rid of marks on Samsung S3's.

Thank you in advance anyone who could advice, no matter how small of an advice it is.

Without more information, it's hard to give any advice. Can you post a photo of the mark?
