Disgusting service and lies

I viewed a 1 bedroom apartment to rent from Rawsons Umhlanga , Charlene was the agent who I was dealing with. There were a few things that needed to be corrected in the apartment ie. the balcony sliding door is broken does not close properly or lock the stove is rusted the window handles are broken the toilet seat is so bad like an unmaintained public toilet , I was promised that apartment came with an undercover parking which is not true. I was promised that a parking would be arranged for me. I had then signed the lease agreement , paid the deposit and advance rental amounting to over R17000,00. It has been three weeks since and nothing has been sorted out. I did not move into the apartment yet. I have been running after Charlene and her boss Gregory who now tells me that I must contact the landlord directly who I managed to speak to once and he was to come back to me which never happened , I called numerous times and I am being avoided by Rawsons and the landlord .. I have correspondence where all of the above was agreed to be sorted. I am now in a situation where I have to find alternate accomodation as I moved out if my last apartment. I am requesting that Rawsons refund me.
