ADT ********* and ******* conduct

Several requests have been made in writing to ADT to cancel my account. The requests have not been responded to and I have essentially paid 2 years for a service that I have not received. A request was sent to ADT within the cooling off period and communication was received from ADT that my contract would not be cancelled. Within the first few days of using ADT, my alarm went off and no follow up calls were received from ADT to check whether I was okay at home nor did any security cars come to my property to check. The alarm system was removed in 2016 and I have paid for the alarm every month since then to date which equates to over R10 000 for a service I have not received. The conduct of ADT goes against the Consumer Protection Act. I would appreciate it if my contract with ADT could be cancelled as requested on several ocassions.
