batteries will show 12 v and still not have enough amps to start the vehicle, clean all the connection points on the battery , and charge it fully, start the vehicle and check again for voltage at the battery posts, you should have a reading of 13.5 to 14.5 volts, if not, yes you have a alternator malfunction,

Did you ask the mechanic to change the alternator,or did you tell him to fix it? I would spell it out to the customer myself(not the service writer) that I would prefer to do the diagnosis,but if they didn't want to pay it,then there are no guarantees,and document this on the back of the repair ticket(saved me MANY future arguements!).If you told the mechanic to fix it,then take it back and say "Try again!".If you said "Replace the alternator" then that's what will be done.If you have no change after replacing the alternator,then you have to figure out what's not making it charge.Verify the large cable to the battery is good with a test light.The smaller connector requires a wiring diagram to diagnose,however.
