I've also had this Scam email and worse they have added 3 months of the Entertainment subscription to my account. It already says that it is cancelled but I now feel that I will need to recheck in 3 months time to check I haven't been charged.
This is so underhand. I have cancelled my Sports subscription.
Ok - I've mentioned this on a couple of other threads.
Mistakes do happen but this one is frankly off the scale and appears to have happened a number of times according to this board.
Can you confirm it was simply the email that was wrong and you didn't actually subscribe customers to a services that had not been consented to ? That's illegal.
I recall some cases a few years ago where customers had been switched electricity providers when all they had done is give their details for more information.
I suggest it's appropriate to formally apologise and not send another ridiculous marketing "oops" email.
