I am getting so fed up with Amex giving me new cards that are have identical last 4 digits as the old cards. I understand their system (how they use the last 5 digits, and how the last 4 digits are automatically generated), but I sure wish they'd change their system.
Why can't they move the "100" to earlier in the number???
I'm trying to complete spend on one Amex to get the signup bonus, and a convenient way to do that in places where I would not have preferred to use another card normally was at some hotels I'm staying at this month where I don't have a card for that hotel program anyway.
I reserved a set of La Quinta brand stays (all the same property) with one Amex card that I got this spring that ends in 100N. Then when I checked into the hotel, I gave them my new Amex card that also ends in 100N. I kept checking the Amex website for the new Amex card, and the two stays I've had at that hotel so far were showing as pending (from the card swipe at check-in), but the charges never posted. Then this morning I happened to check my previous Amex card and the statement that just closed in much higher than I expected. I look at the details, and the hotel posted to that card.
My folid only shows that the card I used is an Amex ending in 100N. ("N" is the same for both of these Amex cards I got this year.) I don't see any way I can prove to the hotel that they used the wrong card, if the last 4 digits and type of card is all they look at.
I don't suppose I could call Amex and ask them to move the charge (on statements that already closed) from the card it posted on to the card that was authorized for it???
I know I can "claim" I lost the card and request a new card with a 200X number. But that won't help in this case, because I would need to use the both of these Amex cards this week on a trip which I'll leave on before my Monday snail mail arrives.
So I now I have to completely shuffle around how I'm going to complete the minimum spend on the newest Amex card, because I can't use it reliably for those La Quinta stays.
