EMail says I didn't pay for iCloud but I did

I received an email saying they could not charge my card for iCloud -- it was to be charged yesterday and I got the email yesterday. But my credit shows the payment. Not only that, but I also have Apple Music and the charge for that went through (on same credit card) and I did not get an email about that. And, when I go to check my account and credit card in my phone, there is no indication that anything is wrong -- in the past, for example, when my credit card changed, it would show that I have to re-enter my credit card details.

I thought it might be a phishing attempt, but all the emails go to apple.com and it seems to know a lot about my account.

Should I worry?

Perhaps the email was a mistake -- is there a way to see if I am up to date with my payments?
