I must say I hav never in my life come across such bad service it is beyond what I imagined. I don't know how many times I called ADT call centre and still today, no alarm installed .I want my money reversed back into my account since the alarm has not been installed , I was debited on the 15thApril R421 and today just a few minutes ago I was debited the same amount what service im I being debited for? U will debit once the alarm is installed until then STOP. when you call me u only call once and you don't even bother to leave a message so please if you call and I don't answer my phone leave a message so that I can call back . Am a professional Nurse working at a Hospital cell phones aren't allowed so it's mostly on vibrate mode I want to know when my alarm is going to be installed its winter now theft is always a problem this time of the year. Am now begging please can someone call me on these numbers *** so we can set up an appointment for my alarm to be installed I will be available on the 18, 19, 23 &24 May, in the mean time I would like my money that was debited to be reversed (R842) and also last year I was debited twice August and September I want that money back
