Late Estate

Absa failed me i submitted my late father's documents to claim the late estate money on 11th February 2020 then they said i must pay R500 for the late estate which i paid on the 12 February 2020..I've been waiting for that money when i call head office they would tell me they are still busy with the process.Now when i go to the branch i submitted my documents the lady who was assisting me there called the head office to find out why i haven't received the money,we found out the money was transferred into my brother's account which he doesn't have the letter of authority to any of those estates.I need answers but they've been promising to investigate the issue till today they are ignoring me!
