Well I was right, can't get the bottom bracket in for love nor money, starts going in and after about half a turn it gets immensely tight so don't wanna force it in case I strip the thread. Won't be gettin built up today! ARSE!!
As for the cost, I spoke to the boss when I picked it up and he knocked it down to £30 for the hassle I've had and said if I take them anything again it'll get done as a priority but don't think I'll bother with them again!
