It doesn't matter if the battery is only a month old, if you have a bad Alternator and/or a draw on the battery it will drain the battery to just about 0.
Have you tried jump starting it? If not please do so.
If it starts and runs fine then most likely you either have a bad (new) battery or a large electrical draw on the battery that drained the battery down.
To check for a battery draw you can use a test light or a volt meter. Remove either the Negative or the Positive battery cable. Then connect either the test light or the volt meter between the Battery Terminal and the Battery Cable. If test light comes on the you have a draw on the battery if using the volt meter and it shows more than 1.5 volts you have a draw on the battery.
Post results of tests.
