Accounts, Billing, & Orders

[Newbee1]

I set up my first device under an email account.  When I set up additional devices, I used another email.  I want to combine the two accounts.  I'm getting billed  twice monthly from same streaming service

This has been asked before - it can't be done.  Cancel your subscriptions on one account and then unlink your device(s) and close the Roku account.  Then perform a factory reset on the devices you want to link to the desired account.
