I receive email saying my account billing info has trouble

Hi there,

I received email supposedly from apple saying my current billing info has trouble needing to update: The content as follow>

"Hello There, 

We're having some trouble with your current billing information.Unfortunately, we could not charge you for your account. 

Please note that after three unsuccessful attempts, your account will have locked and you will be unable to using? Apple service. You can make sure your payment? information is updated."

There's also a button saying "Update Now" but when I click on it, doesn't appear to be link to anywhere.

I tried locking into my account, and there's no problem.

Suspect this is a scam; Try to local Apple email so I can send this message to, but cannot find. How to proceed?

Thanks.
