Charges on paid up and CLOSED credit card

Out of no where today my husband receives a sms to say that R578.34 is outstanding on his Blue Bean credit card. Almost 2 years ago we phoned asked for the amount we had to pay in order to pay up this card. The amount was given and paid. We asked for the card to be closed.<br> <br> Why after almost 2 years do we now suddenly owe R904.79? How the hell is this even possible? I am so gatvol of Standard bank and Blue Bean. You never finish what you are suppose to. You never complete a query, ever. And now we owe you money on a card that according to us is paid up and suppose to be closed.<br> <br> I think it is time to get the ombudsman involved, again. Because someone will reply and tell us how sorry they are about our experience and that they strive to give good customer service...and they will give us a ref number that won't mean anything... this is how you don't do it...
