Worst security even worse admin

After a long battle with ADT in 2022 to cancel my account and clear my name after they wrongfully handed my account over to debt collectors ADT is phoning once again with claims of an outstanding amount on an account I do not have. I have the email records to show that this discussion was already handled and ADT apologized in 2022. Why am I starting this battle again... phonening me for an outstanding amount wich they confirmed was wrongfully assighned to my name....
