ADT Call Center

I’ve had the worst experience coming from ADT customer services call center I had a chat with a lady named Elizabeth Manzi she gave bad attitude and started arguing with me. I got my backup battery installed around Feb-March but I’m already getting notifications that the battery is low so I called to ask what’s the life span on these batteries cause the previous one I had lasted way longer than this one she rep**** by saying “it runs out when it’s finished” and then she tells me it’s because of loadsheding I then told her even with loadsheding the one I had before lasted longer I could hear her attitude getting even worse and we started arguing about the matter
