Western Union Money Transfers Complaint

Western Union Money transfers department,

Domestic (US) money transfer Other service issues Virginia

-, now operating under the umbrella of - - is the company that bills me for water and sewer. I like to pay online ( no one uses checks these days ) but the only way I can pay online is through Western Union speedpay. This service costs an additional $3.00 on an average monthly bill of $50.00. Is it fair to be paying an additional 7 % year in and out on my water bill just so I can pay online? I realize regulating a utility company may be outside your scope ( please direct me to the right place if so ). However, I was wondering if Western Union was providing any kickbacks? Why would the energy company burden customers for years with a very expensive service just to pay the bill online?
