FNB personnel incompetency

I received an SMS reporting *****ulent activity on my credit card. Then visited the Middelburg Midwater branch. My username and password were changed and the app downloaded to enable setting of limits. The app did not make provision for setting of limits. I returned several times to the branch rectify the problem but without success. I then reported to FNB bay e-mail and received a response confirming following up on the matter. It is now again several weeks and can I not the app as required. I identify this as untrained and *********** personnel at this branch and at the call center. Fact is that I don't get this service for free but cannot utilise it to what is offered and charged on a monthly basis. I am a client of FNB for close to 20 years and find the service extremely unprofessional.
