I paid Southwest Gas the full amount of my monthly bill two days before it was due. Three days later I discovered Southwest Gas without authorization pulled the full bill amount out of my bank after I has already paid the months bill in full. So they took my bill amount and double withdrew it from my account after payment was made in full and early. When I called Southwest Gas they refused to deposit the money back in my bank account and said they would just apply it to the next months bill?? I refused that option but they would not budge. When I asked to speak to a supervisor she was extremely rude and offered no solution saying she was not authorized to redeposit the stolen (yes, stolen) money they wrongly withdrew from my account. I tried to explain the problems they had caused to my finances as all funds had been wrongly drained from my bank account due to Southwest Gas and now I had additional charges because when they withdrew the money it caused a check for another bill (electric) to bounce. I went to my bank and luckily they were able to resolve the matter, however it took two months for Southwest Gas to send me a check reimbursing me for the money they literally stole from me. I looked this company up online and discovered they are owned by the Koch Brothers, yes the same Koch brother that on national TV said they could financially bury Donald Trump should he seem to be a real candidate for the presidency (all my political views aside). In addition, although they are Nevada based, they tend to open businesses in other states in isolated areas such as Lake Tahoe and Big Bear Lake, California. One of there practices is to get stock holders in the city to install only natural gas appliances in houses and businesses because it has been statistically proven that people will stay with the energy source of their appliances. Their only real competitors in these areas are the electric company. Which entails changing out all your appliances to electric or propane. Additionally, the Better Business Bureau has them flagged with a warning, and obviously Southwest Gas is not a member of the Better Business Bureau, and they abide by Arizona business laws, have no real oversight, are allowed to randomly increase rates without warning (supposedly because they store Gas for some of these places in New Mexico??) and Southwest Gas suffers no consequences for illegal, corrupt business practices.
In my opinion check your appliances before you rent or buy if you live in an area where Southwest Gas is your natural gas provider. For us it has been much cheaper to switch to electric appliances. Don't expect your local city council to help with Southwest Gas as they specifically service areas where local investors, the big guys, get large kick-backs from lying down with Southwest Gas.
