MK1 gs's aren't all that common thinking this may be my old one, is it blue?
If so then the battery was not cheap! But the alternator seemed like a recon on mine so maybe not.

Couple of things
Can you jump start the car, if so try measuring the voltage to the battery with the engine running with a multimeter, is should be somewhere about 13-14.5 with the engine running just after starting if the alternator is okay.
A 2016 battery shouldn't be dead even if its a cheap one, unless of course its faulty. Can you test the residual voltage in the battery with a multimeter?
Also are you charging the battery off of the car with a known working charger.

Did you get any paperwork with the car, if your lucky there may be a receipt for the battery which should have at least a couple of years guarantee...

Suggest getting the battery charged before attempting any diagnostics, a lot of modern chargers will not start charging if the battery has dropped below a certain level.
Once battery is fully charged, start the car and check the voltage, should be more than about 13 volts.
Alternators will not charge a really flat battery, so you could jumpstart and run, but might not charge the battery

If the battery has been run flat and left flat, even for a day or two, it will be beyond hope. Sulphated to death. You'll need another battery and may be able to get a used one with some life left from a scrappy. I have one in my Vitesse that is date stamped 2004. I got it in about 2006. Still works.
Once you've got a battery that holds charge (should be 12.6v minimum at rest), fire up the engine and you should see a voltage increase to 13.8 - 14.4 v. If not, either the alternator is dead or you have a wiring issue. Most likely the alternator if the warning light is on.
