Standard Bank doesn't want to release my money

R4300 was deposited into my standard bank account, when I wanted to withdraw the money I was notified that my card was canceled in 2019 however the money was deposited in March 2020 - and the deposit was done inside the bank as cash deposit and was assisted by the teller, I went to the bank and they told me the account was canceled last year, they send an email to investigation department and advised that they will call me within 7 days (the money was deposited on 12 March, I went to the bank on 14 March and today is the 27th of April) I've also been following up on Facebook page to this day no assistance was offered
