Reward4Spot.com review: Unsubscribe doesn't work 1

I have used the unsubscribe from five times and now I am getting more spam than before. There is no clear indicator on the website to contact the administration of the website and no way to see how long it will take for the unsubscribe feature to take effect. Since trying to unsubscribe from this service, I have received one notification one per minute and it's slowing my phone down enough that it "freezes" for a few minutes and then works like nothing happens.
