TeleTech Holdings, Inc fired for something I did not do , and no proof would be shown Englewood, Colorado

Teletech .. is a company that had lots of issues. First I got hired in Oct 2008, worked for a year , everyday on time, never late! Got raises left and right. Never did anything different with the Avaya phones we used for customer service work.  After 1 year to the day, of working for them I got a Team lead that wanted to have a meeting... I said ok cool. (gotta throw this in there , My team leader never pulled me aside and said hey you are doing something wrong and I asked in team meetings , if i was doing something wrong let me know. No warnings, no team  lead every gave me any indications that i did something wrong. Always got told I was doing a good job) It was 4 supervisors and they basically were rude, mean , and said I didnt log out of my avaya phone log properly . The last day i worked , i was in tech rooms 6-7 times with tech tickets cause my phone was not working correctly . One of the sups said he was talking to me , which he WAS NOT. I never talked to this sup. He lied and then said are you serious you are gonna say you werent talking to me in chat. I said yes i never talked to you ! Then the main sup said we have screen shots of this conversation, I said great let me see it , cause i know i never talked to that supervisor. Then Igot told , oh well we cant provide that to you !!! Are you kidding me , you are gonna fire me without a cause and just say well this supervisor was talking to you , NO PROOF, never had warnings , never had corrective actions NOTHING... wrongfully accused and wrongfully terminated! This company is shallow . . mean .. the supervisor and team leads do not help anyone!  DISGUSTED!
