Quikr - UPI Fraud Quikr Rahul Sharma

Rahul sharma approached me via Quikr chat and showed interest in buying wardrobe that I had posted. He sent me his my phone number and asked me to call him. Without any negotiations at all, he agreed to a final price and said his staff will come and pick up from my address in a couple of days, but will pay the amount now through online. He said he prefers to use Paytm UPI and I agreed. He said that he have a murchant account, and to make payment in murchant account every time a coupon needs to be generated, and then that coupon will be sent to me over chat.Then I will need to make payment of same amount(x) to him and then total amount (*X) would be credited back to my account.
To convince me - he sent me a coupon of * rupees in the paytm chat and asked me to pay * rupees in the same chat, then my account was credited with * rupees [Obviously he sent * rupees]. The amount of my wardrobe was **** which he agreed to buy. I had other items like study table, puja cabinet, bed to sell, so I asked if he is interested in all those items or not. He said he will buy all. So total amount came to be *****.
Now he sent me a coupon of ***** and asked me to make payment for same amount. Buy my paytm upi was not working. So he asked me to use phone pe upi. So I sent him *****, but money (*x i..e *****) was not credited to my account. I asked him that I did not get my money, he said his phone is not working. Then he asked me if I have any other number on google pay. I gave him a different number and tried the same process again now with *****. Again he made some execuse. Then asked me to use another number with phone pe. I did that again with ***** and again he made execuse. Now I understood that it is a fraud. I asked him for my money back and he said if you want your money then you need to pay me ***** and then it will credited back. Can some help me to get my money back. I have all the screen shot of the payments and whatsapp chat
