I am receiving into my email account at least 5 previous billings every month. One of those bills is the current one to be paid, so I pay it, but then a few days later you send out another 5 previous billings (all paid) in separate emails, an hour apart, and a new one to be paid which is always approximately 50 cents different to the bill sent and paid the previous few days. This is just ridiculous. I has now happened for the past 3 months. How do I get this stopped? I just want the one electricity bill per month to pay. I don't want repeat bills sent every month dating back to October last year.
