Quikrr — quikr receiving, due messages even though i haven't registered in yet

Hi,
From 16/05/2018 i am receiving a message saying that i have rental due of 6, 500 on quikr and if won't pay it by due date then fine of 50 rupees will be taken per day. But i haven't take any property for rent. Kindly look into this issue.

Earlier i used to receive these messages from grabhouse.

And i never registered in such websites.
I am expecting that such things will not repeat again...
