No Rental Relief from Government, Landloards switch off Lights for Tenants, What is Government say about it?

I have been staying in the Building for over 10 years and paying my rentals fully under the estate agent. I have 2 apartments one is my office and one is my residential and my business was hard hit by lockdown as we are in Hospitality and Events Services. I have maintained to pay R4,000.00 per month per unit for all Lockdown months. On Wednesday my meter was blocked from Headoffice and i spoke to Lucas (Group Property Manager) and he said he will not reconnect the Meter until i pay R1,710.00 and i asked if i hadnt been paying for the entire lockdown then he said, i quote "there is nothing i can do my friend, you have to pay); we have been in 4 days without electricity which is prepaid and i dont know how long it will take. So for over 10 months i have paid over R80,000.00 and get my meter blocked for R1,710.00 as per my Estate Agent. We were not given any Lockdown Discounts, and besides all that we have to pay full amounts. Is it a legal right for a Landlord to switch off lights under any circumstance even worse during Corona. Does the Government know, professional Board or any other agent that regulates victimization by estate agencies.
