Monies collected on canceled account. No service but monies collected

I started my relationship.with ADT in 2023. This year I decided to cancel my contract with ADT. I was informed about a cancelation fee which I was happy to pay so that our relationship would end. To my dismay my account was canceled as I called in yesterday and spoke to three different agents as I was trying to get them to put me through to Jo-aan in the credit control department who helped to to cancel this account. This couldn't happen as her phone just rang. Emails were sent by all the ladies as I disputed the fact that my account was canceled yet the debicheck is still active and taking off,R370.00 from my account. Also the Max amount is R 10 000. This would imply that as much as this account was canceled ADT was still collecting funds from me. I am really disappointed and I would like to make other clients aware of this.
