Capitec turning customers away without assisting them.

I bought a new device and i went to the bank to activate internet banking(app). But the consultants failed to assist me and let me go, i then called customer care then i was told to go to the branch which i did again but still they failed to assist me and also let me walk out the banks door without being assisted. Now i don't know who to go to for assistance cause the branch and the call center keep sending me back and forth.
