WHAT IS HAPPENING? WHY AM I PAYING SO MUCH FOR GAS AND ELECTRICITY?

I AM NOW PAYING �218 A MONTH DIRECT DEBIT AND I LIVE ALONE IN A 3 BED ROOMED BUNGALOW. THE PRICES HAVE INCREASED FROM �85 A MONTH IN 2007 TO THE CURRENT RATE. I HAVE GAS CENTRAL HEATING, DOUBLE GLAZING, NEW LOFT INS. CAVITY WALL AND HAVE JUST INSTALLED A NEW BOILER AS I THOUGHT THIS WAS TOO BLAME, BUT IT HAS NOT MADE ANY DIFFERENCE. I HAVE ONE SHOWER A DAY THAT IS A POWER SHOWER AND USUALLY USE THE MICROWAVE TO COOK.....I KEEP TRYING TO TELL EON THERE IS SOMETHING WRONG BUT THEY WONT EXCEPT IT AND SAY THEY WILL TAKE THE NEW PAYMENT FROM NOV 08 AND REVIEW AGAIN IN SPRING 09. HAS ANYONE GOT ANY SUGGESTIONS WHAT THE PROBLEM IS HERE? I AM A DISABLED RETIRED PENSIONER AND AM FRIGHTENED AS I CANT AFFORD �218 MONTH AND THIS HAS BEEN GOING ON SINCE 2006. I HAVE ALSO SPENT �1400 OVER THE LAST 2 YEARS HAVING ELECTRICIANS CHECK MY WIRING ETC.THE NEW BOILER COST �3000 AND NOTHING HAS MADE ANY DIFFERENCE. I AM WITH EON. SURELY THIS AMOUNT IS FAR TOO MUCH. DOES ANYONE KNOW THE AVERAGE DUAL FUEL BILLS FOR A FAMILY OF 4? CAN ANYONE SUGGEST SOME HELP FOR ME.
