Manpower review: Screwed me out of job

Recently, Manpower had me working at Walmart.Com and when I went in to work on Saturday afternoon (3:30-12:00 shift), my badge would not unlock the door for me to go in... had to get the security guard to let me in. When I confronted my supervisor, she handed me a pack of lies about what I was doing wrong in my work, which I knew for a fact, were complete bullschtick. When I demanded to see the documentation she had to back up her claims, she told me Manpower had those documents. After I got home (a 2 mile walk, by the way), I called Manpower, and inquired about the supporting documents. I was then told they didn't have that information, and that I should "get over it". No truthful explaination for my termination was ever given! I have a couple of theories about why they did it... one involving a pre-existing medical condition, and another involving religion... contact me to hear them, so they won't try to sue.
