I posted and ad on quikr for selling my used Nokia Lumia 520 and gave expected price as Rs.4000/-

I received an email from Quikr and also a phone call saying that someone is interested in buying my mobile for Rs.4500/- and also Quikr will arrange a pick up from my home. They will also give me paytm coupons for Rs.250/-''I could not undertsand why the buyer could not contact me directy.
I wrote to support at quikr asking why this is so. There is no reply from the.

Is Quikr themselvesdoing such frauds.
