Alumo energy

I asked for an upgrade on my battery and 4 panels , today the guys came through to install and discovered that the wrong order was sent and the battery was the incorrect one , the installer advised that he will go back to office and collect and be back in 1hr time , i then get a call from Arlyn advising that he cannot do the installation today as the guys are gone for another installation and there is no one available and he also spoke to his senior manager Conna - what customer service is this ????? the people also aware that we have many outages in the area and the current battery cannot work hence the upgrade and my son is currently with online assignments at varsity, now the only date is Wednesday, and nothing can be done --- very poor service and from senior managers to get an answer loke this is ridiculous -
