@Anonymous User Welcome to the community. There is no telephone support (except for NOW TV broadband customers) so you'd need to use either live chat or send a message. You can send the NOW TV Team a message or get to live chat from the Contact Us page
https://help.nowtv.com/get-in-touch
(expand the Anything Else section at the bottom for options)
The other alternative is to pop onto your My Account > My Passes page
https://account.nowtv.com/passes
and in the FAQ section look for 'I think I've been incorrectly charged', you'll find a request form in there you can fill in instead.
