Igm Services — Spam company doing fraud in the name of giving job

I got call from a lady from IGM Services Gujarat. She whatsapp me about the job details and said No extra money I have to pay for the job it will deduct from my salary once and the same things will be written in agreement but in agreement it is written every month I have to pay 6900rs which she didn't informed me. After receiving the agreement call from IGM Services on 11 August within the next 1 min I call back on their all the numbers from where I got call to say that I am not interested in doing this job and I am not agree with all the terms and conditions of the agreement but no one received my call. Numbers were showing switched off. Where calls were going they were not receiving my calls also. The lady named Aditi who gave me information about the job she is all the time online on WhatsApp but her no. is showing switched off. Whatsapp call going but she is not receiving and not even replying. I called on the helpline no they said to mail on helpdesk. I mailed on all the email id's within half hour from where I got mails. Today on 12 August I got call to pay 6900 cancellation charges. I asked them clarification for what I have to pay as I don't want to join such job since yesterday but they didn't they didn't replied properly and said legal action will be taken against you and cut the phone. The lady named Aditi is Still online but not responding. I got mail to pay 6900rs or legal action will be taken
