APPLE STEALING MONEY

Apple does not send you information about payments via text messages, so this looks rather like a scam, trying to get your personal banking details or other data.

Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support

If you see 'apple.com/bill' on your billing statement - Apple Support

As you enabled getting notified by mail, if Apple charges you for your subscriptions, this is the only way you will be notified by Apple about payments.

Identify legitimate emails from the App Store or iTunes Store - Apple Support

The text messages seem to be coming from the card company, without a link to your Apple ID account.

To see a specification of what was charged to your Apple ID account, see: View your purchase history for the App Store, iTunes Store, and other Apple media services - Apple Support.

The unlisted subscription is puzzling, though. You may want to contact Apple Support about that. Contact Apple for support and service (phone numbers) or start your support request online (chat/​email/​callback).
