Which Visa/Mastercard credit card has good US-based customer service

paypal mc - terrible customer service
Lol! Ayy! Someone else ran into the same situation and tried to reach out to Synchrony and PayPal for info and got the same shitty result as I did. Fun fact, the phone reps didn't know anything and I had to figute it out myself.
The answer to your question is that the PayPal MC has a unique virtual card number that is exclusively used for online purchases through PayPal. This is why you are able to lock the physical card and the physical card's number while still being able to use the PayPal MC online for PayPal checkout. I've tested this out myself after not getting any help from the support reps. It always amazes me that the customer support reps don't know about this feature of the card.
