I wanted to like this service, but within 2 minutes of using it I experienced a 500 error. Which isn't a big deal It was however a big deal when it is sending thousands of requests to zendesk a minute and breaking all of our systems. Within an hour it sent over 37k requests to our zendesk instance. There was no way to disconnect from the backend and there was also no direct line to contact support. I love the idea, but I am now cautious to try again.
