Exhorbatant charges for Service fee plus on a dormant account to close the Account

I had 3 banking accounts with Standard Bank and during covid we received a text messaged to inform us that the account is dormant for 6 months, we did not attend to it during that time, also I had been unemployed for a long time, so I was not transferring any money into their accounts, now we decided to close the dormant account, the bank has requested we pay in service fees R70 and a revolving credit and R60 pm month whilst the account was dormant, and in order to close the account they requested an amount of R2300. Also we have moved frm Cape Town and FICA regulations were adhered to by furnishing our new Address,
