Highly frustrated and irritated with Protea Metering

I have been having multiple problems with my water bill with Protea Metering over the last couple of months. My water bill has gone from R158.03 in Jan this year to now R579.49. Every time I called I get different explanations from different people and no one actually listens to what the problem is. I am very frustrated at the fact that no one at Protea Metering can give me a straight forward answer as to why I am paying so much for water. On the 17th of July I was informed that my water consumption is R 1 261 which I feel is impossible and 5 days later I received my invoice stating that I am in credit with R195.46. I understand that the Grand Central is metered daily and water consumption is payable immediately but this is going to the extreme now, everytime I purchase electricity no matter how big or small the amount Protea Metering takes half of it. I never get the full amount for the electricity I purchase due to this. Something has to be done about the process and how things are done for Grand Central apartments as this is becoming very frustrating and I am sure I am not the only person at Grand Central who is experiencing this. I would appreciate it if someone could urgently look into this because if this does not get resolved my only other option would be to move out of my current apartment. This is highly unacceptable
