Rental increase every month

Worst place to stay at honestly speaking. I was happy when I found this place and thinking finally it’s a Social Housing then rent is affordable. All of the sudden they change hot water from meter to billing. I got billed for days I wasn’t in the apartment. I enquired 3 weeks straight via email and in person and get told they don’t have the reading and they have requested and they will email them.i am expected to pay over R250+ of hot water that I was only in my apartment for 10 days. And now am sent a letter of demand and with a threat of eviction. Other part is that access fee for cold is still paid and which means for water alone is half of the utilities I pay monthly. I sent countless emails and no one will help. This is only to mess up my credit and I am paying like someone who is in a private rental. I’m expected to pay close to 5k on a social housing anf when I signed my lease it was a very affordable rental and that was to get us to sign the lease…
