Extremely difficult claims process.

I put in a funeral claim on Wednesday afternoon and I submitted outstanding documents for the claim on Thursday morning at around d 8am. I called in on Thursday afternoon to check how far are they with the claim since I submitted the documents early in the morning. I was then told in the afternoon after I called in that my claim is in the queue waiting to be processed. On Friday morning I called in again and my claim was still not processed and I was then told that the claim would only be processed at 2pm. I am now being told that payment will only reflect on Wednesday but I need the money for a funeral on Tuesday. When I put in the initial claim, I was not told that there was a queue system and that the claim would be done in 48 hours, which according to my calculations would be on Monday morning. Please help me with this
