Appalling and 'unlivable' experience at ithemba properties

Ithemba properties has displayed horrific display of care for their tenants. I have been renting with them for almost a year now, have payed rent on time every month without any issues. Last month I deferred on rent as my debt was too much, however I arranged for a payment agreement but was told to pay an access for them to consider my arrangement, I couldn't and told the building manager I wont be able to, isn't there something we can do, never got a response. ithemba went ahead to turn my electricity and water off. I have emailed and called customer care countless times without any resolution. All my food in the fridge went bad, unable to bath to go to work. I don't think them switching off utilities is legal or am I wrong?
