ADT JHB

I took out an alarm contract with but cancelled it in less than 24 hours. Nothing was captured on the system when i called in to cancelled it and the customer agent assured me that this won't be captured but she **** to me. Three days later i was told i have an account with them and they tried to debit my account but reversed that transaction. I even went to the bank to blocked them from accessing my account. I don't have any alarm system but the just want to debit my account.
