Your address on the national database won't affect us taking a payment from you. You shouldn't be charged twice for your usage - you'll only receive one monthly statement.
It sounds like there's an issue with the third party you're using to pay the bills, we haven't heard much about them - so we can't comment on this. I'd recommend getting in touch with them to find out what the issue with the database is. We can then get this updated, this usually takes 2-4 weeks depending on the issue.
You can send us a message on Facebook or Twitter to get this resolved, if you don't use social media - send the team an email on email@example.com.
