Account on Hold without any reason and can't get hold of anybody

After we have submitted our FICA documents more than a year ago and they have told us in Feb 2022 that all is in order they have decided to put our business account on hold without any reason. To get hold of any person at ABSA is impossible! Branches doesn't answer their phones and if you try the normal customer care line they just give you other numbers to phone without any success. or they transfer you from one division to the other and each just tell you that you are at the wrong division. So what is going on at ABSA???
