Naukri.com — money refund issue

I had got a call from divya naukri.com, she offered me a job at dell india pvt lmt. I agreed and paid 2500, as she assured me that if something goes wrong she will refund me 2500, i got selected in first round but the hr asked me to pay security bond of 10k, 20k or 30k, i completely disagreed to that, first round was normal and with comman questions, how did he just selected me directly without technical round and asked me money as a security bond, i don't want this job and ms. Divya didn't tell me anything about the company security bond,, please stop doing scam and refund my money back m a fresher and not earning yet plzzz
