About experience certificate

Hi sir, Myself Abc , I have issue with my ex-employer.They had terminated me by blamming me about bad behaviour and going against company management decisions although i didnt done any such things.I only request once them during COVID 19 lockdown.my parents are not doing good and i need some more time to take care them and i will keep working from Home some more time during lockdown they also permitted all other employees work from home .that I had worked for xyz company for 1.5 yrs. Now i dont have issue with their decision of terminating me but i have problem with their way of terminating me by wrong allegations.When i asked MD of company as this is very small company hardly 20 to 25 employees in it. So he was not clearing telling me about this..only saying that i have issue with handling your team.So i said i need proper clerification about my bad behaviour. What bad behaviour does i have because its all about my career, my self respect and my dignity but he didnt cleared it.So later on when i was on dinner break .He through my luggage out of office in midnight and told me through office boy that leave the office right now.So he mentally harassment . Next day i wrote him mail about all incident.but its all use less..he is much more egotistic person.Now i am jobless from last 2months .he terminated me during during time .And also issued me wrong experience certificate by stating that i had fight with owner of the company.try to ruin my career and tried every chance to mentally and financially harrash me ..So what do you think should i go against him legal action or nor
