[Resolved]  Quikr — receiving too much notifications

I registered on quikr to find jobs but unfortunately didn't get any suitable one. So, i unsubscribed from their site. But still they are sending emails. Every sunday they use to do this. Not only that, their partner companies also send emails through quikr.com. Even i didn't get any option to deregister on their site. That's too annoying. Please resolve this issue.
