Dating Integrity - Not getting refundable amount back integrity

I had received calls from girl name Drishti regarding personal service. After the discussion, I had paid **** Rs/- of registration charges. After registration, she told me that you have to pay the amount of ***** Rs/-. They said after that amount you will get personal details and location of the girl and within an hour this amount will be refundable in your account. I again paid this amount. After * hours once again I recieved the call from the girl and she told me that you have to pay an amount of ***** Rs/- for verification charges. Once you pay this amount you will get a profile of the girl and her location. If you do not pay this amount then you will not get the refundable amount on ***** Rs/- and also the refundable amount of ***** Rs. Next morning she told me that you have to pay again ***** Rs for your membership without this amount we can not move forward. You will not get all previous refundable amount. So I request her please cancel this process and give me my all money back. Then again she told me that if you have to cancel this process then again you have to pay ***** Rs/-. Once you pay you will get all amount refundable in your account after some detail long discussion I paid the amount of ***** Rs/- on the basis that I will get a refund this amount till evening. After membership, she told me that you will get a membership card and girls profile. But again in the evening, I received a call from guy name Ashish that your process is almost completed and to make an agreement between you and girl you have to pay ***** Rs/ amount. Once the agreement was done with that girl within ** min you will get the refundable amount. But again they had given again some stupid reason and ask me to pay again ***** Rs/-. So again I request them I will not pay this amount please refund my all money back. But they refused to give me all the money back. Please suggest how can I get all the money back? Please help me.
