2 months later, FICA not updated

On 11 December I took the trouble to drive to Lambton from Alberton to provide FICA documents and update my details. I arrived at the branch just after 13h00 and sat in line until after 15h00. I was referred to a lady at the last counter who was being assisted by Susan. I handed in my documents and requested them to update my telephone number and residential address. I provided three documents, they chose the RCS statement. I left the branch as they were locking the front door. The consultant asked me to mail her my FNB statement which I did. She confirmed in response that my address had been updated. In January I received my statement by email still with the old address. I emailed Susan but got no reply. After 3 days I called the call centre who assured me the address on the statement was the old one as it had been changed before the cycle date ended. on 24 January I received another statement still with the old address. I will not be calling you or visiting a branch again since you are clearly not able to perform a simple request. If the FICA documents were not acceptable you should have told me this when I was there or had the courtesy to respond to my mails and advise me.
