Avoid this member at ALL COSTS.
I was selling a Haro Extreme Frame set on the forum and he said he wanted it, but couldn't afford it. So I offered him the chance to pay half right away, and half when he could afford it, with no timescale. He paid the following week whilst I was away on business, so I booked the parcel in for collection for the following Thursday on my return. I told him this and he said he wanted a refund as he was going away on Monday and it wouldn't be there in time. I said that there was no problem with a refund, but he would have to return the frame to me as it had already been sent to our collection depot. I therefore upgraded the delivery to next day before 1pm (at considerable cost to myself) so that it would be there on time. Unfortunately TNT failed to deliver and it was delivered on Monday instead. The driver tells me that the delivery was refused by the member in person and that he was not in fact on holiday. This meant that I couldn't get a refund on the delivery cost. When the frame was safely back in my possession I refunded him the full amount minus the delivery charges. He replied with foul language and general abuse, I have never come across a ruder, more arrogant person in my whole life.
An absolute disgrace to the retrobike community and one I hope you never have the misfortune of dealing with, either on the forum or off it.
