Nedbank day light *******

I have such a huge issue with Nedbank, I phoned them toward the end of April about selling my flat. My flat was sold, on the 19th July 2019, they send me a letter with the balance in my account being R314 889.95 and this excludes R3500.00 that i paid on the 25th of July but the charges R329 412.22 to the lawyers. When I called today to ask about this they said they can't give me any details since they handed all the information to the lawyers and the lawyers are saying I should get it from nedbank. I want my money.
