Money for stock broker account missing

I have recently opened up a stock broker account with ABSA to buy and sell shares, after the account was opened, they sent me a bank details to deposit my funds in so I can start trading.

The person that sent me the account information, sent me the wrong bank account to deposit my funds in to, which was for non-SA residents. Afterwards they send me the correct bank details but I had already deposited funds into the wrong account.

I have been trying to get my money back for weeks now. Every time I ask for feedback I get the same response "the issue has been escalated to our finance team".

I have had to use other funds and deposit that into the right account so I can at least trade but I still don't have the money I originally deposited into the wrong account they provided me with.

I am deeply disappointed in the fashion that this has been dealt with and how unimportant I seem to them, I have been a customer of ABSA for over 25 years and I believed that they were the best bank for me but this has been the worst service I have received from them, it would have been better if I invested my money with another institution if I knew the was going to happen.
