bad business morals

Please assist as the was a discrepancy on my billing for I was on R67 on the 19th of February 2020 and on the 20th of february2020 I get a message that iam on R-960. I followed up and was told different stories up until I was referred to the billing department I was assisted by Christine on which she told me that the is a leak on meter and that she will be in contacted with the complex maintenance guy to go and do the reading on the meter on which that never happened. What is frustrating about this matter is that she told me that she will switch on power and that never happened as in the evening when I got home the was no power and its affecting my appliances and food in the fridge. I tried following up yesterday I was put on hold for more than 30 min and eventually the phone was hanged up and I tried calling again same situation I was on hold for 30 min. I then called the call centre they couldn't help as they stated that this matter should be resolved by the billing department, I hen requested Christine's email address. I sent her the email requesting feedback till today the is no response and my power is off again.
