Poor claims management experience

Submitted a claim for credit life on my vehicle to Absa sent through the UI-19, Certificate of service, proposal for restructuring document, settlement agreement letter, my id and bank statement. They are still asking for a retrenchment letter. What exactly should the document say to confirm my retrenchment and asking for 6 months bank statement, how relevant is my bank statement to my retrenchment? If I don’t know what I am doing was a person it would be Absa and their assessors. Claim pending unreasonably.
