In May if 2029 I was suspended from Fedex ground because they said I had submitted. Dirty u/a when in fact it was never tested. Then they said it was a refusal and that’s why a fail was given . I never refused either , my sample wasn’t enough so they said it was inadequate and was let go with a 12 month suspension. Three years later I’m still blocked and don’t know why or who to talk to on this matter. I was told that I would have to go in front of a sap panel and that costs 900$.what can I do ?
