Electricity being closed

I live at The galleria. My water bill for October was way to high for what we use. Hot water R677 and cold water R407. We are a family of 4 where are adults and 2 are kids. We bath once a day (mornings), during the day kids are at school and we're at school. We wash our dishes once a day and do our washing once a week. We have been using the water like through out and have never had to pay such a high amount. I sent emails to the lady responsible for our unit (Siphokazi) who by the way is so rude, never answers the phone and emails. I asked if they can please send me the statement showing how do they charge for water per kl and the units I used. The statement showed I used 16 units of which 7,07 was for hot water and the rest was for cold water. They sent me pictures of meters I am not sure if they belong to our unit. I decided to not pay money I cannot account for. They have now closed our meter to buy electricity. As we speak, we have no electricity and we're sitting in the dark. Can someone please help with this problem because when I signed my contract, no where it was said that we will have unstable and forever increasing rent.
