Well regardless if I'm seen as a fool or not, I'm trying to be decent about it and give him some benefit of the doubt. If he refuses my offer, I can use evidence against him as mentioned in the thread of tampering and generally suspicious behaviour. This is what I sent him last night and am now waiting on a response:
Hi Xxxx,
I appreciate this has been long winded, and apologise for the delays. But all I could do was wait for responses from the courier and I've shown you all the email correspondences between us. As it happens, I've now heard from them again and they've refused to pay out saying that packaging guidelines weren't followed. This is typical insurance company bull**** because I'd checked several times with the courier service about the way I'd packaged it before I sent it and they said it was fine. You even said yourself how well it was packaged. So they've washed their hands of it and it's now between us to sort out.
Thing is, you've gone ahead and authorised repairs on the assumption that the insurers would pay out, so this is a mistake I'm afraid. The quotation you sent me a few weeks ago amounts to £400 which is very high. This would mean sending you back pretty much everything you paid me while also keeping the unit. That's like me giving the unit away for free. I think you have to agree that I truly have no real proof of the extent of damage. Technically speaking, the unit should just be returned to me and then I reimburse you the full amount. Alternatively however, I'm quite happy to offer money for the repair, but not the amount in your quotation as I don't believe it would cost anything like that. I think you should be looking for a cheaper quotation and I'm prepared to send you £150 for the repair costs. It comes down to either that or sending the unit back.
Cheers, "
