I have this woman I hired

At work who is supposed to start on Monday but she reaches out to me today to tell me that she is in the process of moving and doesn’t know where her social security card is. I tell her that’s fine and that she just needs to know the number I don’t need to see the physical card. And this like 50 year old woman proceeds to tell me that she doesn’t know the number. Like girl I can’t help you anymore
