Aqua water compay horrible company customer service White Haven, Pennsylvania

I sent a letter to the public utility commission's  about the what Aqua water co operates, First there is a bldg. in my town BUT you can not pay your bill there  WHY????? you can only mail it in or use speed pay for $4.oo . then they said the more people that they put in Aqua  (other townships ) the bill will decrease  NOT???? I lost my job my husband is a stroke victim, diet betic and receives a small disability check, There so called medical  help  is for 30 days and the headache  getting it is horrible. I tried to speak with them and the people that are on the other end its like not my problem, just pay your bill or we shut you off. I ask if i can make payments every 2 weeks to catch up the response was we r shutting your water in 48 hrs, if my water is shut off there goes my heat. any suggestions how to deal with a company like this? I agree with someone else who said if they had a little competition the company would be long gone.
