I posted a link to live chat in this other thread you started.
Should the live chat link not open for you, then try a different internet browser with it's adblocking software disabled or perhaps a different device which has an internet browser on it.
MS Edge works for me when i need to get in touch with NowTV live chat web service.
Unfortunately NowTV doesn't have a telephone number for TV Pass customers (only NowTV Broadband customers have a dedicated telephone helpline number to phone 😡).
The early Smart Box with Freeview is the only NowTV device that will get broadcast BBC1.
If this is what you have, then do a retune, as all the Freeview channels are being shunted around between 22nd and 30th June.
