BPO Projects India — offering data entry jobs

I had received a call from this company that at first i missed when i called back i was connecred this lady sarsnya who at first explained me the job profile but didn't tell me anything about the company.
She then later asked me for my government id proof on whatsapp so i gave it to her on the same platform although she told me that i will receiving an official email asking for the same which i didn't when i questioned her she told me that she has sent it and that it doesn't matter i can whatsapp her the proof that i did and after that i received email from her explaining the work which was (Online form filling and postcard work). After i provided her with the id she asked me to provide her details like a personal bio again on whatsapp which i did. Further she told. Me. That she will be come back to me with further details. Now after this she sent me a so called offer letter which was not on the company letter head, it did not have a reference number or a date it was not signed or stamped and my name was also not on it. Then she called. Me and told. Me. That it was a refund policy letter that i would have to pay around 2500 to the company for the training that they will be providing and she asked me if i had any doubts for the work which was not yet assigned to me i mean ofcourse a person would have doubts how can you expect a person to not do a work and say yes i have no doubts. I felt something was fishy so i checked and was not satisfied with the results soni decided to not pay them. By this time the lady had become very coercive and was forcing me to pay her the and kept on asking me how will i pay, she was not giving me anytime to think or process the information which i must tell you is not how hiring is done. Then she kept on sending me messages to pay the amount so i blocked her and within 2 min ls she started calling me. From. Different number trying to abuse me and when i didn't answer her calls. She she me a whatsapp from a different number saying that i was silly and that i didn't want a job so i reported. Her to whatsapp twice and blocked the various numbers from which she was calling. Then i further received coercive emails from. Her abusing me.
I mean this seriously not the way things work. People want to earn money with hardwork in a legitimate manner but such people only harass us and give us mental stress and also wants to leave no choice for us to even say yes or no for a job which is a basic right. I request you all not to entertain any calls from this company and not to pay any money to them.
