disappointed

There is a new application that needs to be loaded to verify students in preparations for the exams. I have had issues with the app and had someone call me to take me through the whole process, she wasnt patient. she wasnt explaining things so i can follow up and she said she will not assist me any further and dropped the call in my ear. i am not happy that when there are changes, and when we are supposed to be assisted, there is no patience in the whole process. how do i get this process sorted if there is no patience among people who are supposed to help? I am very disappointed in all this
