Struggling to have my address changed

I am trying to get Standard Bank Insurance Brokers to change my address and insert my correct ID number on my burial policy. My first email was ignored so I resorted to the telephone. I eventually made contact with MPHO who sadly typed my address incorrectly. I then telephoned again and made contact with Lindsey who assured me the errors would be corrected but that I should 'phone the next day to make sure it was done. I have at this point made 5 telephone calls and sent two emails and still don't know whether my address change has been done as I have had no confirmation.<br> <br> Clearly an address change is quite a demanding effort on the part of SDIB. <br> <br> As I have already used up a considerable amount of airtime, I would appreciate someone advising me what more is required from me to get my details changed.... Surely I would not be required to fly to Johannesburg?? <br> Thank you.
