Name change not reflected

After 4 years of changing my surname from my ****en name to my married surname I have followed up several times with my branch, Rosebank for assistance. They have over the years logged up a call as it was defined an IT issue. <br> <br> Several organisations including SARS now disregard my bank statements because my correct surname is not on my account. I have been informed that my profile has the right details are on my profile. I approached the Centurion branch for assistance and no change was made within a week. With Rosebank being offline on 23/05/2015 I approached Killarney Branch and was assisted by Asanda for assistance. She promised rectification within 40 hours. On Wednesday 27/05 she made contact and promised feedback on 29/05. I followed up with 2 calls and still no response.<br> <br> Who in the organisation can assist me with this issue? After several visits to the different branches I am told its a IT issue but no one is giving me any feedback at all. I need someone to assist me urgently otherwise I will take the hint and close my accounts as this is more than frustrating to say the least!
