Some app or we paise discount from my cridt card haw I can stop this thing?

I'm not sure what you are asking, what do you want to stop ?

If you mean that you have an auto-renewing subscription then you can stop it renewing by logging into your account : Manage your auto-renewing subscriptions.

If you mean in-app purchases then you can stop them by turning off in-app purchases via Settings > General > Restrictions on the device.
