FRUSTRATED DURING THIS VERY CRUCIAL TIME

I purchased a Samsung J4 core in April 2019 it just went off in December 2019 with a battery life of 70% apparently "It just needed a software update" . The phone was repaired and sent back to me. At this current moment I am in isolation awaiting my covid19 test results that was supposed to be smsed to me. You cannot imagine my frustration as the phone just switches off again at 60% battery life and not coming back on. How do I receive my results that I have been impatiently awaiting. How I am I supposed to get to the store to give me phone so it can be sent back.

JUST SO DAMN FRAUSTRATED.........

I do want to apologize to the Ballito Store Manager for losing my cool with her. As she has explained she does not know anything about the phones.
