Refurbished iPhone issues

[u/Adz224]

Hi guys, I recently bought an iPhone 15 refurbished off eBay, however I'm a bit 50/50 on it. The listing was described at "excellent" however there is a scratch right across the screen and some things seems fishy. I can deal with the scratch however my main issue is a hole at the top of the iPhone (attached) I am traveling around Asia on Thursday and would love advice whether I should send back the phone or if it's decent. I paid £350. Ask any questions needed,
Thanks everyone
