ADT:Worst company to deal with. I would never recommend ADT

If i could give then Minus stars. I would. After cancelling my contract, in writing and verbally in August 2023 and the admin lady confirming she has esculated it to the right department. I still receive invoices to pay my installment and now they want to black list me for them not doing their work. I have phoned and asked them many many times to send confirmation of cancellation. Nothing gets done. Gideon Barnard - sale person. Johan du Preez - some or other manager, Shemeena - admin lady - Adt garden route. Worst of the worst service I have ever dealt with. They promise high and low and nothing gets delivered.
