I want my deposit

Moved in their properties a year ago, they promised to clean before i move which they didnt, promised to change the locks which they didnt, promised to fix the stove which they didnt.... i reported all this yhings until i got tired decided to leave their premises. When i left no one was there to make sure eveything is fine, which they didnt even do an inspection when i moved in. They didnt refund me my full amount. I was only refunded R1918.74 instead of R5400. This mafadi nonsense are ******.... DO NOT USE this company its ***
