Absa - Poor service

I have an Absa Student Loan for my son. Today, it took me over 40 minutes via cellphone to find my outstanding balance. The student loan is not available on my banking app. Each time phone you are asked security questions only to be transferred to another department. There is no direct Student Loan contact number. The number appearing on the net is incorrect. I have been banking with Absa for the past 40 years. Absa- please be more professional. Update your student loan account number and also train your representatives. Also ask your Student loan division to send emails and a sms informing clients of balances. I cannot understand why the student loan cannot be linked to the app.
