3 MONTH LONG UNRESOLVED APP PROBLEM

A VERY frustrated customer trying to open a bank account for the past 3 months. I have 20 reference numbers with NOBODY coming back to me. Apparently an IT problem with the app but nobody in the call center knows what to do and keeps “escalating” the matter with NO RESULTS!!!! They are about to lose a young doctor as a customer forever for the most pathetic service I have ever encountered. I will probably move my insurance, medical aid and life cover else where! Where in this lifetime does it take 3+ months to open an account?
