Climate Technologies — Data entry threatening

First they called regarding the job opportunity of some data entry. Then they asked for details and video introduction. After they called about whether I got my id, password and link for work. And told me that I will get the link within a day. But I didn’t get the link and their numbers were unreachable. So, I installed the truecaller then I came to know that all numbers were listed under scam. So I left that thing and forgot about the same. Then suddenly after around 1 week they started to call and mail that you have breached contract and to pay the penalty amount. And now they are sending messages about case submitted against me.
