$4600 bill what the? You won't help me find out why it's so high, but will charge me an extra $366 to check if your meter is faulty. I asked you if you could investigate the bill and all your worker is a smart arse and says okay and I find out nothing is looked at and I'm just stuck with the bill. $4600 you have to be joking? I feel stuck because the people I rent from have had their friends a plumber and an electrician come out and said things are okay??? What am I meant to do, if I don't have electricity I can't pump my water to the house. I don't know what to do, but the last bill was $1060, I can't keep getting these unbelievable bills. Stressed and not sure what to do
