[Resolved]  HDFC Bank — recruitment fraud

Dear sir/madam i had applied on quikr for the post of an accountant in hdfc bank, they took my telephonic interview and i was asked to submit 2000 rs as security deposit and then i was again asked to submit 5540rs. As security deposit for my verification, they had offered me a salary of 17500 pm in the training period and they admitted that their team will check my background too. They had assured me that they will refund me back my money as soon as i join the bank, then for the courier service they again called me and said that i had to pay an amount of 7500 in the sbi account of mr. Prem kumar
Accout number-[protected]
Ifsc code-sbin0004539
That was when i and my father went to the bank i checked the employee code
The one who was in frequent contact with me claimed herself to be khushi gupta, an employee of hdfc corporate office
And at last i didn't pay 7500
But the earlier money that i have already paid 2000+5740 rs
How can i get that back
Whenever i call them their number isn't reachable and is blocked
Can you please help me out
Please suggest a solution for this
I am really in need of your help
