    I'm sure that a good shop would be able to find out what's discharging the battery. You need to find an auto electrical shop or an independent GM specialist and give them a chance to fix it.
    If you have aftermarket equipment like a sound system or alarm system, disconnect it to see if that's the trouble. Or find an electrical shop or GM specialist.
    If you want to find a specialist, here's a directory link for you:

    You probably have a bad diode in the Alternator. The alternator will charge and test ok but when the car is turned off the diode will cause a draw on the battery.

    The fix is to replace the alternator.
