I applied for ticketing executive in Qatar Airways in quickrr jobs
I got a call from them and told i have shortlisted .. they have taken a technical interview through audio call for me and said selected in that
They told me to pay 1, 800 rs for application fees
And after that some training equipment fees 5, 200 rs and now asking to pay 13, 900 rs for bond and agreement fee.
i have paid them 1, 800 and 5, 200 ra . total 7, 000(seven thousand rupees) i paid to them. they told if i cancel it i will get my money refunded . and i felt that its a scam, so i told them that i want to cancel my application and i need my money refunded to me.
they changed the words, and told i need to pay 18% amount for my backstep and cancellation, i.e: 1250 rs
if i pay 1250 rs only, my amount 7000rs will be refunded within 48hrs, if not it will be refunded in 45days.
i didnt get my money back now.

date of the incident : 16/01/2021

i really need my money back i.e : 7000 (SEVEN THOUSAND RUPEES)
