What now?

Two months ago I made an enquery about a problem that I am having with ABSA, on Facebook. The following reference number was assigned to it, (C-***6 ) [ ref:_00D1r1GluM._5005J58BX8:ref ] I was then contacted by Pravesh Bejay, Specialist Case Manager: Social Media Complaints, Customer Value Management: Customer Care who promised to attend to the matter. This was on the 9th of July 2020. Since then I have been unsuccessful to solisit any reaction from either Pravesh nor you Facebook team. Messages are simply ignored. Any advice will be appreciated.
