Hello @KristinS1897 ,
Are you receiving any specific error messages or anything that could be screencapped (without showing sensitive billing data) for us? Otherwise it may also just be some kind of basic connectivity error. Please keep in mind that when I say connectivity error, I'm not necessarily referring to just your internet speed. There are a number of elements that can affect website connectivity and accessibility on an individual basis.
If you're not receiving any particular error messages, nor does performing any basic connectivity troubleshooting alleviate the issue, then I'd recommend calling our Billing team directly so they can securely assist you.
