Unhappy client of Std Bank

I called the call center and requested to speak to a consultant from Card Division with regards to interest charges on my Credit Card as there was ***** on my credit card. The consultant could not assist me and requested me to hold on. I held on for 28 minutes, (picture taken as proof) she never got back to me. I eventually dropped the call. I am not sure if Std Bank is aware that we pay for these calls that we make. How many hours does one have to wait for someone at Std Bank to hear your query let alone resolve it?
