DO I have a case worth looking into?

I was recently fired from my job at Startek Inc. for allegations of Domestic Battery that were false,the person that accused me of these charges no longer works for the company, she was fired because she made allegations after the situation about me in other things to other employees and made a hostile work environment for other agents. my employer claims that it was due to 2 no call no shows my employer knew of the situation that was falsely put against me and had an order of protection against me that did not allow me to call or contact them at any time for a period of a month, I had people call in for me they stated that since I was not calling myself that it did not count. I have come to find out that similar instances have happened and others have gotten their jobs back at the time of my employment I was amongst the top agents in the building I was not fired for any work related instances nor for my job performance. I have been looking for employment but am unable to find work due to this situation and I am wanting to know if I have a case? Edwin M. Bond SR.
