Hello, My name is Nishan Rana and i was cancelled...

Hello, My name is Nishan Rana and i was cancelled by my previous company on 18/01/2022 and my last date is 16/02/2022 in which ethier i had to apply for new job or visit visa. I already got a new job in another company on 13/01/2022 and signed all the contract papers but the new company but the new company has still not given me my e-visa which i ccould show to my previous company and claim my passport. So tomorrow is my last day and i called my new company for e-visa but still they say it will come tomorrow and this is going on from 1month and i had no reason but to apply for my new visit visa which i applied today 15/02/2022 and now my previous company is saying that tomorrow is my last day so the company will deport me to my country or is saying that they will ban/blacklist me because the company will be responsible for overstaying fine. I told my previous company that i have applied for visit visa and visa will come soon and if there is a overstaying fine i will be responsible to pay the fine but still the company doesnot want to listen to me and is saying will ban/blacklist me. I tried talking with the company but still they don't want to listen to me because i have done everything i can to ask for the e-visa from the new company but still i haven't received and i've applied for visit. So my question is if there is a overstay fine is the company responsible or me to pay the fine and is my previous company allowed to ban/blacklist me without any reason?
