Unable to get through to a human on the phone, automated system gives you milliseconds to input your answers using the keypad, confusing menu set up with no number to press to pay for the bill using a card till you get through a second stage just by holding on as a 'vulnerable customer' or an emergency, clear as mud. When got through, Payment rejected as there was an issue with confirming the account/identity, despite me inputting the correct information. I know they obviously don't want people paying by card and would rather I use the web and direct debit to pay but I'm trying to pay on behalf of my elderly mother who isn't a fan of online anything. Also they switched from quarterly payments when she was with SSE to monthly payments even though their own website still says you can pay quarterly and the letter they sent specifically said it will stay as it was with SSE. Incidences of ignoring meter readings submitted and using estimated readings instead, confusing bills and excessive paperwork. Bills received a week and a half late (not postal strike) giving you a day or two to pay the bill before they send reminders, all in all pretty stressful to deal with and clearly not there to aid it's customers, seemingly more interested in deterring them from contacting them in any way for any reason. What a shame this was forced upon her, may have to look around for a different supplier, but they all seem a bit rubbish. Could they be ANY worse??
