Quickr — invalid rental sms

Hi,

I'm receiving a daily sms from quickr saying that I've an outstanding of 14K balance as rental balance. I've never used took a home/shop for rental via quikr. Its asking me to pay before the due date.. Buts there's no date mentioned..
1) I've called customer care but they're asking me to send a mail ID which doen't even have the word quickr. It seems to be an private gmail ID.
2) Submitted a complaint via quickr website but there's no response.

Daily morning sms making me so sick. Please do the needful.

Regards,
Satheesh
