This should be NO STARS. The app is terrible, and has been this way since I joined the smart meter brigade. When trying to top up my meter it jumps about goes off and back on then jumps around some more. I have had money taken from my bank account but not gone on meter, had to chase them up about it. Customer service need to have lessons how to talk to people. A few weeks ago I went away for 10 days with £13 on meter which should have been enough for charges and fridge and freezer I topped up after being away for 8 days. When i returned home NO ELECTRIC food in fridge and freezer completely defrosted and ruined, emergency did not trip in as I hadn't " signed up" for it. I thought that it would be done automatically. Today I cannot top up online as the system is down AGAIN. Also not including the charges how am I using £4 a day for just the fridge and freezer and tv. With occasional airfryer????????????????
