Akbank Mobile App Issue: Unable to Become a Corporate Customer

Hello, I downloaded the Akbank Mobile app and wanted to become a corporate customer. The app did not provide the necessary functionality. I called the call center, and a person named A*** provided incorrect information. They performed an incomplete and erroneous process, stating that you cannot become a customer through the app, and caused me to be victimized. A representative named S*** yelled at me on the phone and ordered me to "go to the branch."
On the bank's official website, there is an image and advertisement in the "Become a Customer" section stating that you can become a customer without going to the branch, but the bank employees do not accept this process. I am complaining because I have been victimized.
