The Google Play Store makes it pretty easy to manage your Robokiller subscription from your device. To cancel your membership, please follow these steps:

Step 1: cancel your subscription

1. On your Android phone, go to your subscriptions in Google Play
2. Tap Robokiller
3. Tap Cancel subscription

Step 2: turn off call forwarding

Follow these steps so Robokiller stops blocking spam calls and handling your voicemail.

1. Go to deactivatemyphone.com 
2. Select your carrier
3. Call the number given

You’ll see or hear a confirmation message when call forwarding turns off.

You can now delete the app.

For more support and other cancellation options, go to Google Play Support.
