The guy is a complete cock. I live local to him (Bishop's Stortford) and have been messed about many times when thing don't fit.
Got to the point of him not answer calls or emails so I tried his home address only to be told he is never there.
Only when I saw him driving in the car park at the local Tesco did I manage to speak to him by blocking in his van, he then phoned the Police when I asked him where my £600 was.

He is a totally tool and you should never buy anything from him.
