[Resolved]  Indigo Airlines — job offer

Address:

Kolkata, West Bengal, 700028

Hi,
On 11.02.2020 i got a call from this ([protected]) number, the woman on the other side (Name isha) claimed that she is calling from indigo airlines regarding job vacancy for ground staff and asked me if i was interested in the job to which i replied yes. She therefore explained me about the job (Ticketing, 10 to 5), salary[protected] and pick and drop policy of the comapay which seemed legit. Afterwards she told me to send identity and qualification documents to a whatsapp number ([protected]) or to email it to id. [protected]@rediffmail.com. And thereafter asked to pay 2100 inr as registration fee within a stipulated time, to all of which i agreed. She also mentioned various payment portals namely google pay, net banking and paytm. Later she asked about my father's occupation and also said that a peson will call form airpot authority of india to for verification.in the evening i sent my documents to the above given number. Next day she sent me the details of the account in which i had to send the money. Later i got another call, this time a man. He said that call was for verification and asked by what time will i be able to pay the registration amount. Later he called again and asked for my blood type. Thereafter they called me several times for payment processes which seemed absurd. Moreover it was disturbing as i was at work. Smelling deciet, i decided not to go foreward with this job offer. On 12.02.2020, evening, around 7:30, the man called again and asked why haven't i sent the amount. I replied due to some personal problems i won't go for the job. He said 'ok' and hung up. Today morning (13.02.2020) at 9:53 the woman called again and asked why i didn't send the money. I replied i didn't want to. She said that the job id is already created so i should pay the amount. I said that i'm no more interested because i am convinced that it is fraud. She then threatened me saying as i have wasted company's precious time my documents will be black listsd for 5 years and also the company will take legal actions against me. And that i will now have to pay 40, 000 inr as a penalty for wasting company's time and that i should visit the nearest police station to collect the notice. She also sent a message stating "this message is a written warning to you that company is taking legal action against as you have wasted company's time in a result your documents will be blacklisted from civil ratio and pay 40, 000/- as panelty and visit your nearest police station to collect legal notice".
I'm now aware that i have pissed the lady.
I just want know whether i should be worried or not.
I am certain that all of it is a scam and that woman isha is a fraud. Still i need assurance. Please help.
