Zulberg Property Management cut off my electricity last night

Zulberg Property Management cut off my electricity last night. They had no cause or legal right to do so. Despite numerous requests throughout the day they have not restored it. 1-I am not a tenant and do not own a property in one of their managed portfolios. 2-I'm not contracted to them in any capacity whatsoever. 3-I don't owe them money for any services either past or present. 4-Their conduct is contrary to legislation relating to property rentals. 5-Despite being made aware of all the above they have with impunity not restored my electricity. I have paid rent, purchased prepaid electricity and neither owe City Power, nor the owner or Zulberg any electricity or other outstanding charges. I am a pensioner of seventy. This is unfair and has caused me distress, extra cost and discomfort. I have done nothing wrong. Yet this is the second day I have had no electricity.
