Renewal of a domain na,e

Hello there, 

My email address is samuel.dunlop@gmail.com. I have been receiving a renewal notice from Homestead about a domain I registered last year. It now says it will expire in four days, but my billing information is setup for auto-payment. Can someone help me to ensure that the domain that is about to expire will auto-renew so that I may keep it?

Thank you!

Samuel
