Standard bank return my money

In 2018, i transfered money (R4 800) from FNB to Standard bank, the Standard bank account had a debit balance. I realised that the account had already been closed and assumed that FNB still had the money on their side. After going back and forth between banks,I got tired. Standard bank even wrote a letter saying that there was no money on their side. this year in 2020, through hello peter, i pursued it again only to realise that the money is in Standard Bank recoveries. Was given an email and number to call, but all are in vain. It has been 3 weeks now, no response not even an acknowledgement of the email. when i call i am losing a lot of money because no one picks up. Please i need my money, its beeen exactly 2 years and the value that money had in 2018 is no longer the same. Tired of these games Standard Bank
