Disgusted in what is supposed to be called service

I have requested for a new battery to be installed in August month, which happened but asked that at the same time they debit my account. I have since then been making endless calls to get this done, spoke to Caitlyn, Kiara, Shayna, Brian, to get hold of Jeremy who seems to be the only one working in accounts. A week later he calls to say he was off sick, no one could tell me that. Jeremy then says he will sort payment as no one else could actually do it. Soon after this is done, I stary getting endless calls that I have been handed over for non-payment yet no fault of mine that they did not debit. This has been going on since installation happened in August. Last week this same battery just stopped working, my alarm system just died..key pad and all. Technician comes out after hours after 2 days after requesting, and I am told this battery was recalled, so he doesn't understand why they did not let me know. This is last week Wednesday. I call Friday to speak to Simone who is on a call and will call back. It is Monday, I do another call, speak to Zitho who says she is not available, but he sees they have booked a technician for Wednesday, that is 7 days since last week. I ask to speak to manager who I am told is Don Jacobs, but he is not available and there is no email address fof him. I am just so sick of all the stories now by ADT....I GIVE UP!!! HOW DO I TRUST A COMPANY TO LOOK AFTER MY FAMILY'S LIVES IF THIS IS HOW THEY OPERATE
