Hi All,
Firstly, the customer has made the payment again, and I have received the funds again.
This was after making it clear to the customer I wasn't renegotiating the price, and they needed to make payment again, or I was coming to get the car.
To answer some of the questions above, the payment appears to have come from a personal account (also HSBC if that makes a difference) as the credit narrative contains their name (rather than any sort of business name, but of course it could be a sole trader account). The transaction type is 'BP' - which I understand is bill payment/faster payment in HSBC parlance.
He made the payment to me, as people do, on his phone while buying the car (and using his security token thing) - so I don't think it would be a BACS/CHAPS payment.
Once I have recovered I will make a formal compliant to HSBC and see what they say (if anything), but I have no bank manager or particular sway. I just speak with the 'phone banking call centre whenever I do call.
How did he get it recalled - saying its a fraudulent transaction - that is my suspicion but I have nothing to base it on, and given he used his security token and his 'phone app how he gets the bank to agree it's fraud - I don't know.
The bank recalled it themselves of their own bat - this is another possibility (after all the guy answered my calls, and has paid the money again) if they thought it was suspicious. However, normally they don't let the payment go through in the first place and you have to hang around while the customer calls their bank and gets the payment 'released'. Just reversing it 24 hours later seems unacceptable.
I may taken some time, but I will post any further details / information.
Thanks all.
