Standard Bank heads in the sand about an Internet Banking Problem

On 27 October 2020 I notified SB Private Banking that their Banking App has a problem. The drop down list to select transfer of funds from an account and to an account has "vanished". Come end of the month and after 6 requests on a daily basis, the problem is still not resolved. This problem occurs on Safari and on Google but not not on Chrome. So it is a SB problem. Has worked perfectly for years and suddenly this problem which they treat with heads in the sand.
