You weren't offering any helpful advice, only your criticism of his choice of work. Obviously if the OP can't manage the repair, he should return the fee, but what he needs is to know how to sort out the problem with this shifter. i thought he was pretty clear about this kind of thing not being his full-time or year-round job.
