Deposit to be paid back.

My daughter was studying while staying in gauteng city college accommodation,New doornfontein in 2025 and the first payment had to include a deposit in which in total was R6000 and was told that I will get the R3000 deposit after moving out early January which never happened...I tried calling them and they told me that I'm not the only person who paid the deposit and who do I think I am to be complaining about the deposit money in which other parents haven't received too...even today I'm still waiting for my money yet there are no signs of getting my money back
