I've drafted up a couple of letters that I'm about to send over to Synchrony bank and a few other banks (including Capital One).
I saw the sticky thread with all of the backdoor numbers for each bank. I was wondering if there's a similar thread on here with addresses that goodwill letters should get sent to? If not, it'd be really useful! I have two PO Boxes jotted down for Synchrony bank right now - not sure which is the right PO Box, so I'll be sending a letter to both addresses, which is a waste of paper and stamps.
