Struggling to get promised credit card since 2014!

I am a client of Standard bank for 32 years! During October 2014 my son and I went to the Woodlands branch so that he can get signage writes on one of my accounts. They offered him a secondary credit card. Since October 2014 I called the client service centre several times and also went to a branch for assistance. They could not help me and said I had to call client services. I called them 5 times and every time they promised they would call me back to give feedback - which NEVER happened. The cherry on the cake was when the supervisor told me on Thursday 16 July that she definitely would have called me back on Friday 17 July because, according to her, this bad service is unacceptable! I am so fed up for empty promises! They are all *********** and clearly no client service exists!!
