Internal transfers from Barclays to Barclays SHOULD be instant! In reality they rarely are!

And an important note [I know it doesn't matter on this occassion as it's YOU putting money in HIS account ] Transferred money [on a Barclays to Barclays transfer - no idea about other bank's policies] can be reclaimed within 24 hours!!

I found this out after meeting a bloke halfway to Somerset to deliver a Mazda 6 and take his Vecta in P/ex, he'd come to see it the day before so it was a case of going out the way to help, not being dodgy.

He transferred £6k which was shown as paid in the morning then the next day was shown as being taken back the same night!!

Obviously I was absolutely fucking livid and was ready to drive straight down to the address he gave in Somerset to get the car back! But it turned out it was a banking error [one of many] and that was when they informed me that they could remove it within 24 hours [which was also them trying to wriggle out of any liability].
