Hi @Anonymous User
Sounds to me it's the NowTV authentication process when checking your bank card when creating & setting up a NowTV account and not related to asking for help.
Out of curiosity what method did you use when seeking help from NowTV ?
There is a section about the 10p charge which is credited back on your card in this help article linked below.
