Stopping user from making in app purchases on a live iPhone app

Hi

I am trying to stop user from making in app purchases on a live iPhone app. What i have done is i made Cleared for Sale: No in itunesconnect product id and Status is changed to Status: Developer Removed from Sale. But still i am able to do in app purchase in the app. Any idea why is it? anything i should do? Last Thureday night i have done this changes in itunes connect. i don't want to delete the product id from the itunesconnect.

Thanks
