Poor service

I submitted my claim for FNB hospital plan on the on the 06 of November 2025. They sent me email asking for Claim form and Doctor confidential form, I sent it on the 4th of December up until today Ive never get any feedback or progress of the claim on the app the status of the claim it says the claim is closed. Ive been calling FNB daily asking for feedback they are all saying they will escalate. Today when I call they said I never sent documents tests and result hence I called them and confirm that they recieved all the documents. I dont know who must I speak to. I called again today I spoke to Lerato I asked to speak to someone in management she refused she pushed to assist me with attitude and promised to drop the phone. Im dissa****ted with FNB
