Stupid Wesbank Employee!!

I recently bought a vehicle with Wesbank and I tried setting up my app, which seems to be extremely difficult. Many years ago I had an FNB, which somehow still shows on there system. The problem is I can't open the app, as the error tells me to contact Wesbank. An incredibly clever Wesbank employee tells me to close my old account on the app first...how f_cking stupid is this guy. I just told him, the app give an error message, instructing me to call them on *** as my access is limited and instructing me to call them....
