Scammers are sending emails which are quite convincing. It's always worth taking a couple of minutes to check the details before risking pressing anything within an email.
Have a look (to the left) at the email I received this evening. It asked me for just £12 and helpfully gave me a "Pay Here" button. However the TV Licence number quoted is not mine, I don't use the email address the scammer sent it to for paying our TV Licence, and the email account they sent their email from is not Gov.UK TV Licensing but instead JosieSorrentino@hotmail.com
