BAD CUSTOMER SERVICES

I am renting the property under this agent, ever since I moved in most of my complaints takes months to be sorted if not ignored. On 25/08/2015 my kids informed me that electricity has been cut off, I have been paying the account on monthly basis without even receiving the statement up until last month where I insisted that I need the statement to know how much I have used for the electricity I was told that the owner said its R645 of which I paid trying to avoid the cut off. To my shock it was cut off . I then paid the account on their behalf but again as always the National letting did not take my matter serious and again now I am still sitting in the dark hence I am paying huge amount of rent without fail. They have no clue of customer service first time I encounter such bad service from an agent I am really tired of being ignored because I am a single parent who doesn't have a man to speak up for me this is totally unacceptable. I am sick and tired of this service I am getting from this agent.
