Worst service possible

I entered into an agreement with ADT September 2021 and when I signed the agreement I was informed by the Sales Person that ADT would come and do an assessment as I had just done alterations to my house and needed to upgrade my security. I have phoned them on numerous occasions, sent e-mails, given notes to the security officers that patrols and to date nobody has come to do an assessment. I then went ahead and cancelled my contract with ADT as they had not comp**** with the agreement. Despite the above they have carried on debiting my account and every month I have to reverse it. I then received e-mails from HTN Attorneys informing me that I had been handed over to which I gave them full details but despite that ADT and HTN keep on hassling as they claim my account is overdue. I eventually got hold of a Khulekani Mo****di at ADT, who I understand works in their Credit Control department and sent him the e-mails. Much was my surprise when after my 16th e-mail Mr Mo****di sent me an e-mail stating "Kindly direct how accounts department can assist you". If that is not the height of incompetence then I don't know. ADT must be the worst in providing service and that is confirmed by the low ratings they get. Let us see if ADT will now get back to me.
