Is it normal that apple supports recommends you to ask old credit card details to your bank?

Big surprise, I forgot my impossible Apple ID password and apple decided to lock me out of my account after trying too many times. For already a month I'm trying to recover my AppleID, sadly unsuccessful. When you contact support, they advise me to go to my bank to ask my credit card details of a card of years ago (it doesn't exist anymore).

And without it I just get back to the "we'll send you an update soon", which then will tell me to wait another two weeks and then go silent so I can contact the support again to guide me through the same circle.

It's also odd they ask for such an old credit card while I had during the last year a new credit card attached to my phone for Apple Pay (my old iphone se died and I bridged 2 months until the iphone 12 mini was out, so I plea guilty of not logging into my apple ID for 2 months).

Anyways, what I would like to know: is it likely that I will eventually get access again to my old Apple ID? Or is it likely that I'll never get it back?
