ADT is a ****

ADT and it’s employees are very bad. An additional service with extra charges was added to my account without my consent. I then decided to cancel their services, they really didn’t want me to leave and phoned me more than twice to convince me to stay. At the end I was told that the service will be terminated end of this month and I won’t be paying anything from October going forward. To my surprise, I get an SMS yesterday saying that my debit order will run on the 30th because the 1st falls on a Sunday. I then to call to check if the message was sent in error to me because I won’t be paying anything, only to be told that though the service will be terminated, the billing was not cancelled and they will take my money. I am now told to wait for 7 to 14 working days because of their incompetence. Why can’t they speed up the refund seeing that I didn’t do anything wrong or just stop the damn thing immediately ? I followed the process and my notice period was more than 30 days. I don’t want my money to be taken for a service I don’t get anymore.
