I'm probably being really thick here but I just can't wrap my head around the logic of it. I pay my bill by monthly instalments at an agreed rate. Got an email the other day from my electricity provider to say I had a new bill. So I looked it up online and there's a figure in minus numbers. I'm hoping this means they owe me money??🤞🤞🤞 (p.s. have tried to phone them but have up after holding on for 20 minutes 😓)
