Suddenly the meter readings went sky high. Our usage habits have not changed. At first we thought it might be related to daylight savings and the free zone might be off by an hour. Now I see by the comments that it has occurred for a few others as well. 25 G is not very much for a family of 5 but we managed just fine until a couple of months ago. Now this allotment is gone half way through the month and either requires additional purchases or down time for the rest of the month. We are new customers as of June 2014 so the equipment is new. We have had enough time to adjust the bulk of our usage into the free zone so we're not going over budget. Please research this as I find it hard to believe so many people are affected by this all about the same time 2 months ago.
