Global Account Statement History Issue

My husband has an FNB Global account where we transferred some funds into around the 15th of July 2021. We require official documentation from the bank such as a statement FOR EACH MONTH that the funds have been held there (Proof of funds) urgently. An agent told us that they cannot assist and we cannot get these documents as there has been no movement of funds in the account for these past few months. Even when I download an interim statement from online banking it is blank with no information regarding the funds that have been sitting in the account. These are simple basic services that I need rendered and I am not getting any joy! I need these statements extremely urgently.
