SAB has an appalling customer service

I am utterly disappointed with the fact that SAB has not been able to address my enquiry that is pending since last year November. I have lodged a complaint about the bad receptionist at the Sandton branch and I have exhausted my airtime calling and being sent from pillar to post. I even sent emails with no response. No one wants to take accountability and ownership of my enquiry. My request is simple as I would like to be linked to their head of marketing and advertising.
