ADT debits money without permission - shocking service

My tenant requested technical asssitance from ADT, and the order was that the payment was to be made by the tenant via EFT. ADT never followed up on payment with the tenant, and the account wasn't paid by the tenant. This morning ADT debited the amount of R1,192.04 from my account. I phoned to request that it be credited immediately. The accounts person, Lazarus, was so rude - didn't even want to hear what I had to say, just kept talking without giving me a chance to speak saying that ultimately I am responsible for the invoice as my name is linked to that account. This is shocking to say the least. Not only does ADT debit money from my account WITHOUT my permission and for a service that I never requested - and then the service agent in the account department refuses to let me speak to supervisor because "it won't change anyhting".

ADT, this is shocking. I want my money back!
