It's OK. Please Check anywhere you have purchased domains. Many sites are actually godaddy resellers websites. They can be called ANYTHING (i.e. 123SampleDomains.com) and you probably purchased a domain or hosting from them.
All my DNH*Domain/Hosting charges are from www.OfficialWebDomain.com (which is a reseller at great prices) and are valid renewal charges in my case.
You most likely received an email from the (name of where you purchased domain/hosting) on the same/near the date. If you didn't make sure that you don't have an old email address in your account as people change their emails and wonder why they don't get the notice of renewals.
Again, CHECK ANYWHERE you have your domains/hosting/websites and you'll probably see the charge for auto and manual renewals. When you have a DNH* charge it may be with your 'other' domain account and probably not a godaddy's main website account.
