Balance Due

Hi, to whom it may concern. 

I was notified through my email that I was going to be charged before or the day of 04/10/20. It said to my bank account number ending in 7822. Which is not the ending 4 digits of my card number. So I am confused and concerned as to why it says that. Is there a way I can fix the issue? Please get back to me when you can. Thank you for your time.
