Awful customer services.. Had an issue with the in home display which does not link with gas meter.. In home display flashing red battery… sealed unit, they told me to change the battery or buy a new in home display which they even said would not be compatible with the old meter… well EDF installed this.. I was fuming being messed around and fobbed off!! Switched to octopus and wow what a comparison, they are very helpful, obliging and friendly and efficient.. The bills from EDF were too high, I was £2,000 in credit and they took the whole lot… I am ripped off totally, that’s my money that I have worked so hard for and I’m struggling on top of everything.. Disgusting attitude to their customers and I dare say they look after their shareholders! People will leave in droves and damn good too, shocking behaviour and no loyalty.
