[Resolved]  Quikr India Pvt Ltd — cheated, product delivered to someone else

Ad id[protected]
I buyed this and called quikr doorstep and they told me it will be picked up on 18sep 2017.
But in 19sep 2017 a quikr representative named manish called me and says we are cancelling your order as seller sold this product to ankush tyagi i said don't cancel it, but he third time called from his own mobile number n cancelled it.
I called quikr doorstep and they said 3 transactions were made on same ad id one by shashank from ghaziabad.
How can 3 transactions be made on same ad id?
Seller told me it got picked up on 18sep 2017 from him.
I made the payment but they cancelled my order and delivered it to someone else.
What kind of service is this?
