As a phone repair tech, Samsung phones are some of the easiest to repair. Especially for batteries or (if you can get Samsung OEM parts) screens.
I highly recommend you take a look at installing the new battery yourself if you're able to be precise with a screwdriver. All it takes is the aforementioned screwdriver, a hair dryer/heat gun, and an old credit card.
The only parts you'll have to buy are the battery and the water resistant seal for the back glass.
Would this happen to be Breakers waterpark? If not, I guess it's just a common story lol
Gone but not forgotten is Gameworks. I still have a card with $7 on it that I'll never get to use
