Received my Mac in good packaging with no visible damage. But battery is not working at all. It remains at 1 % and never charges. Mac restarts immediately when removed from AC power. So it’s completely useless. How is it possible that  Mac with such an important defect was tagged as “excellent”. What testing was done?I am returning and didn’t realize earlier that there is no option for replacement and I need to manage my return myself by sending a courier back to seller
