MY FAMILY IS NOT SAFE WITH ADT

ADT IS THE WORST SECURITY COMPANY EVER. I have been charged excessive response unit fee since end January. I contacted ADT and requested copy of the receipts that showed they came to my place 7 time as they claim, they have only came once a month. The consultant advised they would credit my account for the following month as they see it was a mistake. I called again in February and spoke to a manger who advised they would sort it out and it has since happened 2 times more. My battery no longer have sufficient power to last the loadshedding. My alarm will go off every time the Loadshedding power returns. I will always answer my calls to confirm even though they would call 10 minutes after the alarm goes off. I have once or twice given the wrong password to test their response, the armed reaction unit would arrive after 10 to 20 minutes(which I have complained about). For the past 3 months I have been charged an additional R126(funny how is it the same amount) for excessive response unit which has never came to my house or leave a receipt to show they did come. Last night I realized the reason I'm charged an additional amount when the alarm goes off, ADT would call after 15 minutes and that time the reaction unit is already at my house even though I have cancelled the unit on their automated call. It means if there was a ******* at my house my family would be in danger because you only arrive after 15 minutes. PLEASE ASSIST IN REFUNDING THE 3 ADDITIONAL FEE, R126, AND CANCEL MY SUBSCRIPTION WITH IMMEDIATE EFFECT. I HAVE OPTED FOR AN ALTERNATIVE.
