Problems confirming payment do get raised here from time to time, here is an example and I recall a more recent case too, but they were fixed by calling up. I'm not a big user of this facility since it can't be combined with all fares, but on the rare occasions I have used it, then at least on the main website it's confirmed fine and the hold fee refunded a few days later.
