OK THIS WAS MY FIX....
I GOT ANOTHER WARNING ON MY PHONE - IT FINALLY LET ME REMOVE MY CARD on my phone BUT WOULD NOT LET ME ADD THE SAME CARD WITH A NEW EXPIRATION DATE because it said it had expired (which it had not.
SO I DID THIS THAT WORKED!!!!
I got on my laptop and went to (fyi i was on a laptop but not a mac but...)
https://appleid.apple.com/account/manage/section/payment
This will take you to
Payment and Shipping - Media Payment and Purchases.
It said I did not have a card on file and
I put in my info.
Obviously - make sure you put the billing name your card and use the 4 digit year.
And....shazam!!!!!! My nightmare of a month is finally over!
Apple immediately sent and email that my info had been updated.
I thought about going to desktop because I just couldn't erase the existing card (that of course was not expiring)
Now, my final thought. Lately banks have been reissuing expired cards with the same account number but a different expiration date. I'm guessing this is the real problem. I could be wrong but the above worked for me.
