They have over charged me, via green network energy. We have no meter readings to give to them as GNE turned off the meters, 6 months after the government switch to edf they drop a £525 bill on with no proof or evidene or anything. first it was "no we have meter readings" then it was estimated, and when I as for proof, the only manager who can deal with this disappears and calls be after the customer services centre closes and tried to have a conversation with my voicemail "the customer does not respond, so i am closing the call" still waiting for someone with a spine to contact me
