Spent about half an hour going through the different options, trying to figure out how to get a live human being. Eventually I won through (wooohoo!). And now, in case I wake up tomorrow having forgotten, the cheat code is:

up up down down left right left right b a start

1 - (HSBC, not HSBC Banking)
2 - (credit card, not loan applications or whatever)
# - (don't input credit card number)
4 - (other card services -- which didn't have any indication that there would be a person on the line!)
