Hi there! I understand you're unhappy with your MonoBoost subscription and want to cancel it. I’m here to help you get that sorted.

To start, have you already tried canceling the subscription through the app or the website? If you haven’t, I can guide you through the steps to cancel it quickly on your Android device.

If you did try and ran into trouble, please let me know what happened or if you saw any error messages. That way, I can tailor the solution better for you.

It asked for the bank card that I used for to pay for the subscription;then it said that did not work

Thanks for sharing those details. It sounds like the MonoBoost app is asking you to verify the bank card you used for payment, but it’s not accepting the card details you entered. Let’s work through that.

Here are some steps you can try to resolve this issue:

1. Verify Card Details: Double-check that you're entering the exact card number, expiration date, CVV code, and billing address as registered with your bank. Sometimes a small typo or mismatch can cause rejection.

2. Use the Original Payment Method: Make sure you’re trying to verify the exact card you used to subscribe. If you have multiple cards saved, try selecting the specific one linked to the subscription.

3. Check Card Permissions: Some cards have restrictions on online or app transactions. Contact your bank to make sure your card allows transactions for subscription services or app payments.

4. Try Another Payment Option/ Method: If the app supports, try using a different card or payment method to verify and cancel the subscription.

5. Clear Cache and Update App: Since you’re on Android 10 and using a WebKit browser environment, clearing the app cache or reinstalling the MonoBoost app might fix any glitches blocking card verification.

6. Cancel via Mono Dashboard: If the app keeps rejecting the bank card, you can try canceling your subscription directly in your Mono account dashboard by going to the "Plans & Billing" section, scrolling down to manage your subscriptions, and canceling there1.

If none of these work, don’t worry — I can help you look into any other options or get you in touch with MonoBoost support for further assistance.

Could you let me know if you’ve tried any of these steps already or if the app gave any specific error message when rejecting your card? That’ll help me assist you better!

It asked for another card. Then it rejected that card also.

Thanks for letting me know you tried multiple cards and they were rejected as well. Since the app is not accepting any payment cards for cancellation verification, this issue might be linked to how the app is verifying your subscription or the payment source on the backend.

A common cause of these problems is that subscription cancellations are often managed by the app store account (like Google Play) rather than within the app itself. Even though you use MonoBoost to track subscriptions, to cancel your actual paid subscription you may need to go through your Google Play account settings.

Here’s what I suggest next on your Android 10 device:

1. Open the Google Play Store app.
2. Tap your profile icon in the top right corner.
3. Select Payments & subscriptions > Subscriptions.
4. Look for the MonoBoost subscription in the list.
5. Tap on it and choose Cancel subscription from there.

This method avoids the need for payment card verification inside MonoBoost since your subscription billing is handled through Google Play.

If you don't see MonoBoost listed, or if it shows as already canceled but you're still being billed, please let me know. In that case, we may need to contact MonoBoost support directly at [email protected] for personalized help with your account and payment issues2.

Would you like me to guide you step-by-step through canceling via Google Play, or help draft a support message to MonoBoost?

Are you satisfied with this next step suggestion so far?
