ADT Debiting My Account 17 Months After Cancellation and System Removal

ADT continues to debit my account 17 months after cancellation and after their technicians physically removed the system. In 2024, when I moved premises, I met with ADT representatives who removed the security system from my old premises. During that meeting I clearly informed them that I would not be installing a system at the new premises, as I had decided to proceed with a different security provider. I also cancelled the contract in writing twice, including in September 2024, when I notified ADT that I would be vacating the premises in October 2024 and requested that the equipment be removed and the contract terminated. Despite the system being removed by ADT themselves, and despite the written cancellation requests, ADT has continued to process monthly debit orders. In February 2025, I noticed that I was still being charged and raised the issue again. I have since sent multiple emails and attempted to resolve the matter by phone. Last week I spent 43 minutes on the phone with customer care, only for the call to be disconnected before the issue was resolved. To date, ADT has debited R21,918.70 from my account after the cancellation request and after the system had already been removed. For context, I run three businesses and employ nearly 60 people. One of my businesses still uses ADT services. The account in question relates to a separate business where the system was removed and the premises vacated in October 2024. As a business owner running multiple operations, I simply do not have the time to repeatedly chase companies to action written and verbal instructions, especially when the system was already removed by their own technicians. I am requesting the following urgently: Immediate closure of this account A full refund of all debit orders taken since September 2024 Written confirmation that the contract has been terminated An explanation as to why my cancellation was never actioned Given that the system was removed by ADT and written cancellation was submitted, the continued debiting of my account raises serious concerns regarding unauthorised debit orders and internal cancellation processes. I would appreciate urgent assistance in resolving this matter.
