Automatic Cancellation

How is it possible that I return all of the equipment I purchased from Simplisafe, they credit me for that return, and yet they continue billing me for monitoring services?  I have been billed for three months of service after returning the entire system.

I should have caught that sooner, but frankly wasn't looking for the charge on my credit card as I assumed they would connect the dots.  Either they are conducting bad business by continuing to bill for a service that they know can't possibly be utilized without the equipment or, their basic technology isn't good enough to connect the dots between an equipment return and the billing department.

They know I wanted to return the equipment and why, as I had to disclose the problem I was having in order to get a return authorization, yet for the next three months after my return I keep getting billed.  Not impressive.
