I've completed the filing,Drug test, Background check and My starting day is today 10/22/2020 but I haven't got the confirmation email yet and everything was done on the 10/11/2020 can someone please tell me or contact me and let me know ?

The possibility that the email is wrong is so it is best to ask there because almost all applicants are accepted .

Show up there, and explain the situation to someone up there

Just go over there if you know your schedule. If you call me I can explain it to you better
