Account and contract cancellation issues

Good evening, Kindly refrain from sending me messages that I have an outstanding amount due on an account that was cancelled due to poor service. Go and check the history of the accounts and complaints and cancellations sent. I have been called by one of the managers regarding the matter and was to resolve it. The Worst thing is that I keep receiving messages to test the alarm. Which alarm as am no longer your client but with another service provider? stop being *********** and sort out this nonsense.
