You should just go in, worst they can possible do is send you back home. If # given is not working. That your only choice. I just went in today for first time for 2302 (pre-employment & drug test)…. Good luck
Nope sent me back said to keep trying or email which I have been doing. Don’t know why they giving push back I’ll keep trying and signed up for the next test just in case again. Persistence is key
