Samsung Incompetence

I recently received an insurance payout and they delivered me Samsung S20 FE using Ram, after using the phone for a day I realized that a brand new phone battery does not even last me a full day and the phone gets extremely hot. The phone specs state long battery life, I did troubleshoots to check battery usage, I even started using the phone on battery saving mode however this does not even still last me a whole day, this usage check is done without using wifi and Bluetooth.

I have called into Samsung and was advised that I have to take the phone to a repair center whereby they will do a fault report than send report to the Samsung head center and than a decision will be made to whether a new phone to be issued an this could take up to 7 days. I however am not able to be without a phone as I use it for my authentication to login at work.

A phone that is not even a month old to be exact the phone is 14 days old, I was told I can not have an immediate exchange done on it.
