addressed to who? no one I can call?
Creditboards would probably have an address. Always better to send a GW letter but can't hurt to call.
I had a clawback of $2.50 on a closed amex from the staples fiasco. I just noticed yesterday and paid it ASAP. Today I got a notice that they reported it to TU. How do I get it removed?
