Plenty of threads with this error. No need to raise another one as it won't help on staff from fixing it.
If I were you keep an eye on this link which displays the service status with any known faults etc.

There has never been a number to call NOW for TV support. The only way you can get phone call support for NOW is if your with BT for NOW.
Believe it or not, it’s fact bud. The only phone support you get directly with NOW is for broadband only.
For any form of support for TV it’s live chat or email. Which is more than what Paramount+ can do as it’s only web forms for support.
