Change my business banker immediately

During the course of last year, i had logged a complaint with Nkhluleko, (client service manager) requesting that our business banker be changed immediately. i has told by nkhululeko that he would look into the matter and get back to me. a couple of days later, he did get back to me, assuring me that i would get better service from our existing banker. no change of our business banker. 8 months down the line, i am still experiencing the same s&*%5y service as i have received last year. is our business banker a ghost employee? she is permanently on leave or just never available. emails, voice mail messages and phone calls just go unanswered and no reply. i am really disgusted and fed up with Standard bank. a company car needs to be financed, additional petrol cards to be app**** for, credit limits on company credit cards needs to be increased...but this woman just does nothing. sick and tired of you standard. your level of standards and client service has dropped drastically. i will await your automated response.
