I am receiving two separate bills for family Apple Music, one to my American Express and one to my debit card, this looks to have been happening for several months and I don’t know why. Would like this corrected and a refund of the overcharges.

Re: "I am receiving two separate bills for family Apple Music"

We are all Apple users, like yourself, in the community, so we have no access to your accounts or details.

We'd like to help however.

You might want to contact Apple's Billing and Subscriptions team:

There is a "Get Support - start now" link (online chat, phone, eMail etc., or an app) at the bottom of their website.

If you prefer: There are links on the website to just cancel one of the subscriptions, and request a refund ...

(yet there may be a limit on how far back you can be refunded.)

Else, you could phone Apple support:
