Hi zhanna185,
Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐
We're sorry to hear there has been some confusion over your billing.
When moving home, you are essentially starting a new account which is why you'll end up getting a double bill as your first. When your services are installed/activated you’re assigned a billing cycle in our system. On average it can take 16 days to create your first bill, in which time you’ll have been receiving services from us.
Your first bill will have charges from your first day of installation, plus your month in advance. On top of this there will be an admin fee plus any pro-rate charges. If there has been any over payment on your account at the previous address, this will be credited to the new account and come off the first bill.
We wouldn't be able to offer further specifics on any bills until they've been generated so it's best to let the system do it's thing. If there are any discrepancies, or concerns, pop back and we can then look into things for you.
Many thanks,
