Whatsapp Feedback for Notification

Everybody uses Whatsapp. Its the best app for chatting and my favorite too. I personally don't like the "Notification reminder again and again even after deleting the whats app notification" feature. Its really irritating , don't you guys think so? I am facing this in Android Mobile Nexus 5. I have sent a mail to Whats app regarding this, lets see what happens next. :)
