Southwest Gas needs better math skills! Equal bilking, excuse me, I meant billing means it goes up when it should go down and goes down when it should go up. I seriously believe their bill is not actually equal because they make more money the way they do it and it is NOT in the consumers best interest. How difficult is it to average over 12 months from prior usage rather than this every 3 to 4 month fluctuation, they can do it, but they won't because they make more money changing it as 'they' choose rather thanks actually averaging it. It's a scam like ALL public utilities! As a 'public' utility they should do right by the public!
