Standard bank inefficiency costing me my money

I live abroad and I cannot access my account statements, the App and let alone my balances. I pass all the security questions and I have been contacting them for months now and no one is assisting me. They put me on hold for hours and hours. I'm currently using a number that's not a SA number, please reach me via my email or on this number +86 ***. I want to be able to receive an otp so I can access my bank app in order to see what caused all my money to disappear. I have still been trying to call them to date but I am put on hold for more than 10 minutes most of the time and that is very costly. I have also never received a reference number from them but I do have a recording of one of the calls I had with one of their consultants
