Unable to view archived statements

I recently had to acquire a statement from March for proof purposes. I logged into online banking and was unable to recall any archived statements. I phoned the help line which told me that my option to receive archived statements was switched off. and to inquire at my branch. I went to the branch in Vanderbijlpark, stood in the queue for an hour and Hloni at customer services was quite shocked to hear my query. She informed me that she has never of any option like that which needs to be activated and she cant even access my statements inside the bank. This is quite a concern as this is after all a system implemented by the bank. I had to eventually leave due to other obligations and Hloni said she would phone me back regarding the query. After a few days past, I never had any feedback from Hloni and decided to email the complaint department. The complaint was accepted and i was contacted 11 DAYS later via email by Caleb Buys whom informed that the complaint have been resolved. I disagreed with the way in which it was handled and the time it took to get back to me. today i tried to access my archived statements and guess what, they are still unavailable. If my own bank cannot assist me regarding a process, implemented by them, unbeknownst to their employees who cannot access a client's details inside the bank, should I rather consider a bank which is able to?
