Accidentally Reported Text as Junk

I went to delete a text message and instead accidentally reported it as junk. I read on somewhere on this forum that this has happened to a lot of people and the way to fix it is to open your Apple ID on a different device and then text the number that you accidentally reported as junk. However, I don’t know what the number was because it’s text messaging from my doctors office. It’s a different number than their office phone number. But I get important messages through there, so what do I do?
