company fired me out of blue

context: i work on contract bases remotely. article 4 of my contract states they need to give me 1 month notice and compensation before any termination. However today i was in a meeting with a colleague on teams, when suddenly my whole accounts were logged out and blocked access. i was confused so reached out to hr. hr answers and said "oh your terminated when will you return our stuff(laptop, mouse)?"with no explanation or any other thing. i asked for explanation and told me to call another guy and hanged up on me without clarity, a bye or anything else. i called, sent email and message and they ignore me leaving me on read or no answers. this is pure humility and respect. how can i take it to court.
