CSL Plasma reviews

I had an interview with them (Southfield). A couple of days later, they called and said they accepted me and we discussed all the details of the position. I gave my two weeks notice at my current job and was ready to move but then they call me a week later and tell me I'm sorry they can't take me. They didn't give me a clear reason why, and I felt like they were hiding something. They just kept saying you can apply again in 6 months. Pathetic.
