Canceling a service is often one of the most frustrating tasks of consumer life, which commonly gets people so mad or tired that they just give up. Big corporations create all kinds of machines and obstacles to make people quit trying. To counter their tactics, we decided to play the same game. The Canceller is a bot that integrates the powerful artificial intelligence of IBM Watson with Amazon's digital assistant - Alexa - and Google Cloud to the benefit of consumer peace-of-mind. The result is an unyielding and purpose-driven bot, capable of calling companies' call centers and navigating past the endless machine protocols to talk directly to human representatives. It never gives up. Ever. And it gets better. The longer The Canceller is used, the more it learns and the smarter it becomes.

ReclameAqui have always been the most effective weapon for consumers to solve their problems with big companies. More than 85 million people benefit from its services every year. However, it was time to push ReclameAqui's efficiency to the next level. After all, by analyzing more than 10 million complaints on ReclameAqui’s platform in 2017, we found more than 1,5 million complaints (over 4.000 every day) from customers frustrated by their attempts to cancel services they no longer want. That's why, more than exposing companies' bad services, we'll now give consumers an innovative weapon to solve one of life’s most frustrating tasks: cancelling a service.

In order to understand how to execute such a complex project, we studied the process and the obstacles that big corporations create to make the job of canceling a service unbearable.

More than 1,500 hours of test calls to companies' call centers, endless programming hours and a complex combination of different technologies went into making the first real cancellation contract performed by a machine possible.

After all data gathering, the second step was machine learning, training the bot to a properly data interpretation and response.

On the other end, the first customers to use The Canceller were selected from ReclameAqui's database - Latin America’s largest database of consumers' complaints.

Using an algorithm, we were able to identify the customers who had complaints on record about difficulties in canceling their contracts, and offered them the service. They only had to access the web app, fill in their data, authorize the Canceller as their legal representative and choose the service to be cancelled. Whenever a cancellation was successfully confirmed, a push notification was sent.

So far has achieved the remarkable number of 92% of accuracy on cancelling contracts.
