Britannia Industries — Fraud job

I saw a post and when I contacted to that number she said there’s a vacancy at Britannia as a supervisor post. Are you okay with that post ? Then I said yes I am okay . Then she told you will have interview tomorrow, I said okay . She said hr will call and take the interview. Then very next day I got a call from unknown number and he took my interview and he said you are selected and he told the next steps that girl will tell you . After that she told me give 500 rupees for registration. I paid after that . Then after that she said give your documents and an amount of 2500 for medical . I paid then she said in 3-4 days you will get call letter at your address.I waited but no call letter or joining letter came . Please see to it Britannia.
