Q: Why When I click to pay securely for my repair and complete the form, it says something went wrong

So basically, yesterday I called Apple for setting up a repair for my phone. Then they email me with a link to fill out my payment info. But after I complete everything and submit it, it says "something went wrong...We'll have everything fixed and back to normal soon". So the website crashed? for 2 days?  The transaction is going to expire next week that's what I worry about
