Cannot give a meter reading without calling and waiting half an hour to get through. The call centre is so noisy I cannot hear or properly understand. I raised a complaint and the woman I spoke to just argued and threatened to give me a bad credit rating on Experion When I asked to have the complaint taken further she put the phone down on me! Unbelievably poor customer service I have two meters and one reading was well below their estimate so they altered the previous reading so the balance was the same?? Did they not realise they send me a pdf that can’t be changed so their on line bills now don’t match the pdf they send each month
