Quikr — fraudulent message

I have never used quikr and hence i don't have an account. Initially got a message welcoming me to quikr. I ignored it considering it to be a wrongly received one.
I am receiving a message asking me to pay my outstanding rental dues of 16500 and with an added penalty of 50 rupees.
I am not the only one who is receiving it and it's a serious scam because clearly you guys are trying to loot people who are unaware of it. My phone number is [protected] and i hope that i don't receive it anymore otherwise i will be forced to file a complaint in consumer court.
