ABSA totally unhelpful

I have recently relocated & rented a house in Table View. I went to ABSA bank Table View, with the details & was told that they will not change my address without a copy of the 24 page Rental Agreement! They refused to accept Page 3 of that Agreement, which gave fully signed details of the owner, address & my details. I own both a lucrative Savings & Investment accounts, for well over 20 years & get treated like this!! I would really appreciate it if somebody from ABSA will assist me as I do not believe that my full 24 page 12 month Rental Agreement is of concern to the local branch.
