How is your day going?

Say you want a break down of the whole bill mine was because they changed for gas card to metre I asked to speak to manger I wasn't happy i was angry I blatantly said I'm not paying she came back said they wiped it ! But she was trying to say it's my responsibility I was like do you think I live mansion so if you don't use gas alot say you want breakdown of the bill because it's impossible to use that amount when was your last gas bill ? And how much did you pay and you what to know how they came up with this amount contest it unless you heat 10 rooms and live in a place then I'd understand they have made a mistake ask for someone to come out read your metre or send a metre reading in they tried to get me to do a payment plan I said no way this is wrong
