My safety jeopardized by ADT!!!!

I'm applaud by the service this company renders their customers who are paying for a service and trusting in them to keep their households safe(its a security company after all). I'm a Soweto residence by the way, and I'm just like any other customer on your database, I approached ADT seeking for some relief in protecting myself and my belongings on my behalf and after today I'm not so sure if that's even possible anymore. I left the house going to work at around 5h20 and for some reason I delayed leaving the house and that's how the alarm went off, seconds later I receive a call from ADT checking if I'm okay and being responsive I confirm all is well provided my security pin to cancel the dispatch from the "response team" all was okay so I thought, minutes later my next of kin calls and asks me if I'm okay to my surprise they called my NOK I've already left the house at the time. I checked my phone I did not receive any missed call from ADT. When I returned home I found a note at my gate saying they were here to check if everything is okay at 6h23, and for the life of me I noticed my kitchen door was open, these guys managed to open my house and left my kitchen door open and nobody cared to inform me, by the way the "love note they left me shows they arrived an hour later after the alarm went off" it means my house was left wide open for ********* to do as they pleased for 12hours with nobody to bother letting me that they opened my house to check if I was okay. This is unacceptable. I don't believe what happened was right, I feel violated, unsafe, and for the life of me should anything go missing I will hold ADT accountable because they now have access to opening my house and leave it unlocked when they found it locked. I'm shocked to say the least and I have proof of what transpired today, I need answers as to why this officer Themba left my house unlocked and how did they not report to me that they were here and find a way forward on having the house locked or secured after their inspection/patrol.
