Electricity shut down

I stay at Spitskop Ridge No4 and my electricity was shut down yesterday, apparently i owed R1325 even though i've only stayed there for less than 19 day. Today when I went to their office, they tell me that it was the previous tenants' bill, they didn't even apologize instead the receptionist swore at me in Afrikaans thinking I do not understand. I asked to see the Debtor's controller. It took 15 minutes for her to agree to see me only to tell me that she won't give me a note or letter stating that it is the previous tenant's account. Somebody clearly didn't do they're job properly. I have stuff in the Fridge that have now gone bad and I want to know who pays for them? And how is it okay for a receptionist to swear at me?
