I am on a fixed super green tariff but octopus seems to want to constantly raise my monthly payments by at least double the amount of what I agreed to pay. being on a low income this is totally out of my budget . they have tried to do this twice now and I have only been with them for 10 months. I thought this company was supposed to be better for people who have less incomes so unable to be with the "big 4" energy suppliers, but it seems that now they have started to grow, they are beginning to get greedy and more money driven. I give monthly meter readings as agreed but my bill says it's an estimated bill ? this I don't understand as it should be totally accurate with the readings given should it not ?
