I'll be taking someone with me next time as the trouble is, even if someone tells me what to say/ask, I'll have no idea whether what the garage goes on to say is correct or porky pies.
They checked the brakes as I mentioned, when I got there, that the wheels had been making a noise on the way there.
I'm still going to give them a quick ring tomorrow - if I don't, nothing will happen. If I do phone, the worse thing is nothing will happen but something might.
Straws... clutching... I know :)
