Discovery banks unhelpful business ethics

I absolutely am disgusted by discovery bank.its been months now that the bank cannot help me.i transferred money to a wrong bank account which was a Standard Bank account after calling discovery to please assist to reverse or put a hold on the money they said it was done I called them back on the Monday which as two days after the person said that the money has been released into the account after numerous times of trying to get help eventually some at a Standard Bank branch assisted me and advised that my money is sitting in a account of a person who has passed on and advised I should tell discovery bank to contact Standard Bank on my behalf to assist.i then call discovery and got the run around again and eventually they gave me a number and said I must call it and come to see it was a number for there IT and the person cut my call.The exact amount was R37500 it’s been months that I cannot get my money I run a business and this is honestly torture
