I have a beef with my local Australian bank, the ING (of Dutch fame). Their login system consists of your "customer number" (printed on the back of your debit card) and a 4 digit numeric PIN. Yes, 4 digits. In 2019. To add a payee to your address book the only auth that happens is over SMS; to actually transfer money out of the account you can select any existing address book contact with no further verification.
I like their product offering (cheapest / best in class locally) but this is such a worry to me. I've repeatedly talked to their customer support about this issue (and their Twitter is full of complaints about this) but they keep giving canned responses and redirecting to their "Online Security Guarantee" https://www.ing.com.au/security.html. Any ideas how to get through to someone who understands what's going on, before I grudgingly take my business elsewhere?
