Hang up, call again is something of a mantra for FlyerTalkers. However I suggest writing a letter and making a specific offer. Ideally, you should complete a trip on Southwest and THEN write a letter asking for your points to be restored. That would give the person responding a solid new reason to overrule the default and the prior decision.
Your odds may still be less than 50% but if you are flying anyway it's worth a try.
