Cut my water and i never skipped a payment

Last Week Tuesday they cut my water, I went in on Wednesday to confirm this and was told that I was in areas because they did not receive payment for the whole of 2014. I took out my laptop to show them proof of payment and requested them to please reconnect my water, they said they cant reconnect it I need to pay 50% of my areas, I said that I am not in areas because all payment has been made, now because it was not reflecting on their systems due to whatever reason that means that they don't have proof and therefore cannot reconnect my water, they did not want to take the proof of my laptop they wanted hard copies, I explained that its hard to get leave then I had to beg for an email address, I finally got one and emailed the proof the very next day, its been more than a week, I have kids at home, my water is not connected as yet and no response on my emails with the proof they needed to sort this out, I cant understand why I need to suffer because their systems doesn't show payments and ALL payments has been made.
