Hi @Aneesa
If it's TV related and not NOW Broadband related, then live chat would be the best option to contact NOW.
Click on the green chat online button on this link page below or alternatively message them using the web form on the same link.
Do you have more than one NOW account and also have a payment pin setup on each account ?
