What can I do to fight this case

I was stopped by a coworker going on break to tell me her manager emailed her that anyone who is not following the social distancing will be sent home my reaction was the manager is not leading by example and I asked her why hasn't everyone gotten the email as we have separate managers we go on our last break together and further discuss the same things and I told her I was going to go to my manager about to see if it is true because everyone including the manager that sent the email was not following this new rule as we are talking finishing our cigarettes a last walks up behind the co worker as if she was not going to say excuse and bump right into her the only thing that came to my mind was dang she wasn't going to say excuse me and who is she I've never seen this lady before I smoke everyday even so never seen her anywhere break is up I ask my manager through skype to speak to him privately we then go into a room and I asked him was this rule true and his response was No and that if I dont hear anything from him or his manager dont worry about anything and what the other manager did was wrong and that he will bring to management I finished my shift I get a call while I'm heading home from my contractor asking was I still at wells fargo and what time does my shift end I answered then I was told I will get a call at 530 that they wanted to make sure I was home I pulled over and called this lady back because at this point I'm interested in why my contractor is calling me and why they had to make sure I was home so I'm waiting to be transferred then she came on the line and said kiona I said yes I was calling you earlier to inform you that we are ending your assignment and i asked why she said because u were overheard bad mouthing a manager and disrespecting wells fargo I said that's untrue and I discussed the incident today with my manager she asked what did he say I told her that he had agreed with me she asks so what happened and I disconnected the call because my sister who could hear the call got irritated and starting speaking out loud so then I tried calling my manager and text no response the next day emailed both the lady that called and the my managers manger asking how I can get my things no response this was Thursday my assignment ended friday I've tried reaching out about my personal things like pictures and my belated grandfather's things that our important to me so today is Tuesday april 28th and I've just called the contractor and left a message and email no response I've also learned that the co worker assignment ended as well but due to the conversation outside about the same incident that happened inside that she was overheard calling a manager stupid the reason she was let go in which I know for a fact we did not call anyone a name let alone said the word stupid at any point and time of all this My ?s are can i fight this What steps can i take i feel like i was not wrong in this situation and I'm tired of people lying on me and I'm taking all the negative outcomes
