At what banks can I cash physical EE savings bonds? Especially with a new account?

I use a local credit union that never answers the phone and makes no mention of savings bonds on their website, so I have little hope that they cash them.

Looking to figure out where else to go, figuring there would be a list high up on Google that answers this question, but have found this info surprisingly difficult to find. General guides read like most banks will refuse to cash in physical savings bonds for you at all, and most of the ones that do require you to have had an account for them for months/years already, can only cash in small amounts, etc.

Thanks for any help given!
