I had this same issue, you just need to show up in business casual attire at the time specified in the text and when you get there have the people at the window fix your email address. They had the wrong email for me. Bring your ID, birth certificate, social and diploma. Good Luck.
I got the call and text to come in for the drug test but no email. Can anyone please forward me the email so I know what to bring. Email address is bsmithtsi@gmail.com.
