My hard-of-hearing elderly husband was approached by two men who knocked on the door of the rental house he was remodeling. They gave him the impression they were from NIGas, providing their annual check of rates. They promised to lower his rate. They were very pushy and were not concerned that he was confused by their visit. They did not identify themselves. A few days later my husband received a phone call from a person with a very thick accent he could not understand. Today we received notice from NIGas that our service has been switched to RPA. I am contacting NIGas to switch back. In the meantime, I looked up the rates. NIGas is 8 cents per them. RPA is 12.9 cents.
