Buys a TITANIUm brake caliper kit costing £146 for a GSXR1000 (09-11) and said it didn't fit and I should send another. He had a different type of bike, which he never said what.

I said return for a refund or a swap for the correct parts.
He then got extremely angry. Sent a lot of abusive emails and raised a dispute with Paypal. I said again, return for a refund.
I phoned paypal asking what the deal is and they said he had to return the parts for a refund. In a furious last message he said he didn't know how to return the parts and had thrown them in the bin. So I left it in Paypals hands thinking they'd side with me.
They refunded Gerald Bruce and I lost £146 and he had a Titanium brake caliper kit.
To make matters worse he had the gall to buy 2 more kits from my site for a different bike and emailed me telling me to hurry up and send them as he had a race.
Do NOT sell to this person. He's a scammer and a thief
