Well, went to the Police, but seemed like as soon as they heard it was about eBay they didn't want to know and referenced me to get a solicitor for a civil case or whatever. They didn't see the pics I printed off as they seemed to just want to get rid of me, but I kept explaining it all and saying how it is now completely destroyed and useless. The guy did go off to check with 2 other people though, including 'the sarge upstairs', but apparently there is no evidence to suggest there has been criminal damage, and referred me to the Citizens Advice Bureau.
I figured that they will be more likely to listen as they have half our drop in sessions, more than enough time to actually go through it all properly, and if it does turn out there is a case for criminal damage I'm sure they will reference me to the police themselves or something and they will actually act on it. By the time I got there though it was closed as it shuts at 2pm, so I'm just going to have to go there tomorrow.
I cant believe how useless people are being though, especially the police. I did say I have photos to prove he has damaged it. There was also a girl in there complaining about an officer who didn't seem to care when she reported something as well, so perhaps they are not taking as much notice of things as they should. This is a real downer though. I just want someone with authority to actually listen to the whole story, look at the facts, and say yes you are right. Hopefully the Citizens Advice Bureau will do this!
The guy in question is eBay user: ptgurn_123. Avoid this user! Or at least make life difficult for him at any opportunity!
