Horrible housing agency

I rented a house in Reservoir Hill, Durban, from 2022 April to 2023 March, I’m November 2022 the house was ******, someone broke into the house and stole my tv, laptop, iPad Air, iPhone XS Max, backpack and an external hard drive, this happened while I was away, the agent said the place was safe and has never had issues for the past 10 years, but when I went to open a case, the police told me it has not been even a year since the house was broken into and the landlord didn’t fix anything, I had to fix it my self, the agent kept promising to contact the landlord but never did until I fixed it, they knew how the house is and even the people who lived there before me who also got ******, the lease agreement stated that the landlord is responsible for paying back my goods if damaged or ****** due to him/her failing to disclose everything, the agent ghosted me and the landlord as well, I wrote to the head office and they told me that’s not their problem, I should talk to the landlord, even when moving out they wouldn’t give me all my deposit, they ignored me.
