Deposited money into a closed standard bank account

I deposited R2000.00 to a standard bank account on the 24th of January 2020 and later that day i was informed by my friend who i was depositing the money to that the account is closed.

I then called capitec last week to request a reversal and i was charged for it.

It has now been 10 days and the money has still not returned to my account and when i called capitec yesterday i was told by the consultant that the payment shows as successful on their side and therefore there is nothing they can do
