Iso Air Services — asking for money for job recruitment again and again

Address: Kolkata, West Bengal

I have received an email from iso air services after telephonic interview held.
In this email it is asking for documents submission and fees of rupees 600. So i have filled the fees through upi in the bank account of the iso air services.
After that they want me to give more 1600 rupees to get the job.
It seems like a fraud company. Please get my money refund back.
I need help sir please.
The details of their bank account are:
Bank name - state bank of india
Bank a/c no. - [protected]
Ifsc code - sbin0001720
