Just turned down a new pupil, wanted hourly lessons for his wife at 7.30am. I explained I don't start until 9.30 that way pupils are having to sit in the rush hour traffic.
He said he booked and paid for 3 hours  first  lesson free, with a chap who runs a Nationwide school,  but the instructor didn't turn up. When he complained they said it would take 9 weeks for them to look into it.
