Mahindra And Mahindra — Fraud job and ask for money

I found the job directed applied for the same then I got the call and they asked me for documents verification after that they told me there will be telephone interview and then I got to know that I m shortlisted
So I had to pay rs 3000 as courier charges which will be refunded on joining date this charges are for uniform and everything they said so I paid the amount

Later they said I hv to pay laptop charges of rs 7500 only dn I'll come to know in which branch I'll be working in
N only than my courier will be dispatched
So I got doubt cz they were asking higher amount
I asked them that I m not interested in it so refund the amount paid
They are saying only when I'll pay full amount I'll get the refund
