I get it... Yeah... A huge disaster for both public relations and potentially the business relationship.

The updated information clarified the relationship... And if that had been posted from the beginning nobody would have contacted the bank (as it was clear they were far down the chain). As such, the bank would have had no need to defend their brand and this whole mess could have been averted.

From the supporting evidence provided in the later update... It appears there is a business process and multiple contract relationship in place though. Just the sharing of that information was done badly. Very badly.
