Trying to remove RoboKiller from iPhone it is canceling all my calls

Nice to meet you, *****!
I should warn you that removing a RoboKiller is a pretty complex procedure.

First, let’s cancel the subscription to Robokiller:

1. Open the “Settings” app on iPhone
2. Tap on your name at the top of settings to access iCloud / Apple ID settings
3. Tap on “Subscriptions”
4. Choose “Robokiller” and then tap on “Cancel Subscription”
5. Confirm that you want to cancel the subscription to Robokiller

You can also cancel Robokiller subscription through the Robokiller app or website, but it’s best to complete the process from the Settings app since you likely signed up for it through your Apple ID and the App Store.
Please, do this part and notify me when it is done or you will got any troubles with it, alright?

Thanks!

Maybe the subscription was paid in advance, so you still have access to it.

Next, let’s disable the Robokiller call-blocking service and functionality:
Open the Robokiller app and then tap on “Settings” within Robokiller
Choose “Help & Support”
Choose “Deactivate This Phone”
Follow the instructions within the Robokiller app to deactivate the service

Tell me when it's done :)

Got you
Have you canceled a subscription with them?

Great
Finally, delete the RoboKiller app from iPhone:
Locate the Robokiller app on your Home Screen
Tap and hold on the Robokiller app, then choose “Remove App”
Tap to confirm to delete Robokiller

Keep me updated please

So its removed now.

Is there anything else I can do for you today?
