I recently had the pleasure of using the chat support when my physical card stopped working (the card was just messed up, the account was fine). The person was just weird and had no idea what they were doing. They were asking me questions like "are you sure the store supports Apple Card?" Do you mean Mastercard? Yes, they take Mastercard. Then they tried to tell me what I was wrong, and the card was working fine because they saw transactions a week ago.
I didn't realize there was an automated "request new card" button, but eventually I found that and got a new card.
I was recently told at an A&W that they all took Apple Pay but not Apple Card. So i was like this person is an idiot and tapped my watch and sure enough, it didn’t go through. Tapped another MasterCard and worked fine.
