Pathetic Service by stargas and lack of customer care

I purchase a gas cylinder from Star Gas. When I changed to the cylinder they delivered, I found that it is leaking. I called in as early as 8 am on Monday, they promised to come out and replace the cylinder. To my surprise, no one did, and no one bothered to call me until I called again today (5 May 2025) at 11:50. They still told me lies that management will call me. Their concern is about protecting their reputation, yet they are not worried about the hazardous nature of a gas leak in my house. What a Pathetic service
