Incompetence and inconvenience

My statements for all my accounts have always been sent by post to my residential address. When I got my second car financed through Absa, the statement address was changed, without my consent to my PO box number. When I realised this I called the call centre who told me to go to a branch with my ID and the issue will be resolved. When I got to the branch they told me that I needed proof of address in addition to my ID. I came back again a few days later and was assisted by the white lady at enquiries who after asking for assistance said she had changed all of my accounts back to the home address. When I received my latest statements, they are all still addressed to the PO box instead of my residential address. Firstly, I never authorised anyone to change the address on my statements - quite obviously one always needs the residential address to be displayed because of RICA and FICA legislation and I took the time and effort to go twice to a branch and this has still not been resolved. Sheer incompetence! I expect all my accounts (4 of them) to be changed back to my residential address immediately and I will NOT be further inconvenienced by going into a branch
