ADT putting unauthorized transactions on my account

ADT just bills account and deduct money without any authorisation. All remotes for alarm system stopped working at the same time, they confirmed that the issue was not batteries but system was no longer communicating with the remotes. When we reported that they charged for that service, which was due to their system error. I disputed the charge, wrote on the technician document and did not sign the invoice. They still went ahead and charged my account. They also charged for something that I have no idea of what it is. This is a big ****. They will always put charges and go straight to the account and deduct amounts that were never signed up for, for a debit order. I have to query this with my bank as well because I never agreed to these debt orders. Now I understand why people believe other service providers are better than ADT.
