Ok so I did kind of open ourselves up for it by leaving a telephone number in the ebay auction, but seriously, would you ring up at that time of an evening without emailing first to ask if its ok to do so?
personally I think its rude to disturb anyone past 10pm when you dont know them, even more so in response to an advert, and more so again on a sunday evening.
Pffffttt
Right I feel better now.
For the record I simply asked him to ring back in the morning - Politely
