A has demanded payment from B of an amount of R50,000 which he believes B is owing. B has checked its records and has paid the amount in the bona fide belief that the amount is owing in terms of their contract. Unbeknown to B, his bookkeeper, C had already paid the amount a week earlier by way of an electronic funds transfer into the account of A.
