National new meters double usage

I just got my new bill from national grid and it is more than double from any other bill over 13 years,i have been using less electric than ever and they say it is not the meter,i am not paying them anything until they correct this problem,i see other people on the web saying the same PSC better get on this one,they are ripping us off,anyone else in the area with the new digital meters let me know if you are having the same problem. clanc914@verizon.net
