I'm not getting what I'm paying for monthly

Hi all, my name is Simangle Nkosi and I'm a tenant at Lustre House Johannesburg living at unit121, I first moved in at Lustre House on February 2016. After 5:days of moving in there there shop owner underneath our room reported that there was a leaking to one of the pipes and they came and tear the walls down and from then i 've been asking the care taker to replace or call in someone to fix the wall but nothing has happened, now these 2 holes has brought nothing but the smelling of dirt from inside, ****roaches and u can even hear the water passing thru pipes from the above down. So yesterday I saw care cater and asked him if is there is a possibility of me moving to another unit and we went and view unit 108 of which I was happy to move at and today I went at afhco officers to inform them since they haven't done anything about my problem, they told me to pay R750 to move to another unit. I was so upset of the money making **** because I never had a problem with my place until they decorated my walls with huge holes. I now want my deposit in full or to be moved to another unit. Thank u
