They told me I had a job on Thursday. Sent me there Friday morning. Than called me the day of the first shift 5-10 min after i already showed up and told me to go home. They did not tell me if I had the job or not or what was happening. After multiple days and multiple attempts of finding out what's wrong it took them untill Monday. Only after I tried to contacting them they simply say that the job is no longer available with no explanation of what happened.
