Let down by Rosso Corse - where else to get a service in London?

So I turned up at Rosso Corse this morning at 10.15 or so to drop my bike off for it's pre-arranged service (spoke to them on Tues/ wed) and no one was there! Phone just rang out (i could hear it from where i stood outside huddled against the cold..)

Anyway, waited for over and hour then finally gave up. Made my way to work VERY late, almost too cold to stay on my bike and not in the best of moods.

SO...I was wondering if anyone had an opion on a) whether this is just a one off and i should just re-book with them or b) whether there is somewhere else that would be good to take it in London (i'm North london so would like something as close as poss). I've heard bad things about Metropolis and Daytona so just really unsure

Appreciate any pointers,

A cold and unhappy Clo
