Ordered gas for our bulk tank on 30th December when guage was at 25% in line with Avantigas process. Called Avantigas after 15 days to advise of no delivery and tank reading going down. Last week and this week, called Avantigas to explain that reading is near zero and that we have 2 people in household who have had transplant surgery with being immune deficient. Today 23rd January, called again and was told that they could not say when a delivery will take place, they cannot tell me what is wrong and then hung up on me in mid conversation. Not sure what to do next.
