No. They don't charge for any such thing. you go to your Payment Method tab and just change (edit) your card, your number and the expiration date on your own. 

No charge at all.

No but they would like you to replace it with at least one card on file. But as a former employee I can tell you there is NO CHARGE for removing your card.  here's a suggestion: Add a PREPAID CARD instead. that way if you don't have the money at the time of with drawl, you don't get charged an overdraft fee. I use my Cash App Visa and I use to use a Prepaid Greendot Card. Absolutely no overdraft charges and they can be used as your primary card.

No.  Just add your new card and make it "primary".  Then delete your old one.

No, it's free. Why do you think they would charge you?

Never, why would they?

No they do not.
