mortgage and postal address not matching

I am disappointed,shocked but not surprised by a matter that came to my attention. I recently took a better look at my home loan statement and was appalled to see that my old home address was on the statement. After raising this matter via social media i thankfully received feedback quickly which was promising but led to a dead end. After explaining the situation my wife and i am told that when we app**** for the home loan we submitted a different address to the one we living at now,the home loan address to which the loan is allocated to. I need someone at the mortgage dept from absa to explain to me how we ended up paying transfer duties but the old address is on a statement for a home we no longer residing at?Explain to me how it makes sense for absa to drop that ball? Now we being told to go through a Fica process. This reminds me of a time absa offered me a credit card.When i collected it i did the whole fica procedure.When i tried to use the card it was declined and was told i need to go to a branch to do the fica process after doing that to receive the card. This is a totally unnecessary inconvenience to go into a branch to have this done.
