Incompetence in resolving technical issues on mobile app: Funds transfers

From the end of August 2019, I am unable to transfer money from my loan account to the cheque account using the Absa mobile banking app. However, the same transaction is successful using a laptop/desktop. the problem was reported to Absa Private Banking and Absa Internet Bank and although the agents are trying their best to be helpful in resolving the issue, the support from the technical team to address the issue is severly lacking. I was told the root cause to the problem was identified (two weeks ago +- 10 Sep) but the corrective change is still not implemented. This is reflective of lack of customer service and no regard for positive customer experience. The technical teams has no idea of delivering service and leaves the customer facing staff to explain the lack of competence from the technical team.
