POOR CUSTOMER SERVICE

I have been a client of Standard bank for over 10 years, I transferred an amount of R 170000 to another Standard bank account using my Ned bank account, the person can not access the money because they are saying they are investigating at their ***** department. I have supp**** all the relevant proof that it was sent from my account via email. the people I have been talking to are sarcastic and don't see the urgency of the matter. they say they are still busy with the matter but won't state when it will be resolved. I asked for a reference number and was told they don't have one because there is no case opened. asked for a manager and was told there is no manager around. really disappointed as I have never had any issues with the till now.
