The issue is not whether your line is working, it is whether you have a line at all.
Do you have a place in your property where there is a phone socket? If so, it is very likely there is a line behind it, going back to the exchange; and if so, your NowTV installers will get it (re)activated by BT Openreach, and get your socket changed if needed for the latest type, as it will likely need to be for broadband.
But if you can’t see anywhere that a line comes in, best let NowTV know in advance. We might hope that the presence or absence of a line to your property is something they would check in advance as standard, but it won’t hurt to ask, if you can’t find a phone socket anywhere in your place.
Set a Payment PIN on your account so that no-one but you can buy memberships on it.
Check your bank accounts monthly for any other unexpected payments to Now.
That way you can at least nip them in the bud, while you and Now figure out whose fault they are.
