How to delete my kik account on my iPhone 3GS?

I received the email to confirm and I want to delete my account. I scrolled to the bottom and it said " deactivate account " so I clicked it and it said it was deactivated. However it will still let me sign in and it still shows it on my friends account.

Seems stupid to delete 1 you could just block every1 on there and then just abanden it + if you don't go on it for a while it will get deleted or you could just delete the app. Have fun bro!

Oh just reinstall the app?
