Why say 15 working days when Nedbank doesn't work at all?

I was in an accident last weekend and I reported my claim the following Monday 29-05-23 because the call centre was closed over the weekend. I was advised that an assessor would be sent out in three working days and that I would be contacted on 01-06-23 to hear the outcome of the assessment. I did not receive a call. I called in on 01-06-23 and was on hold for 22 minutes before I got cut off. Then I called again and was on hold for 28 minutes only to be advised that the assessor did not go out as yet, please call back tomorrow. I called the following day 02-06-23 and was on hold for 48 minutes only to be told that the assessor did not upload the findings on the system and that I must call back again the following week Monday to find out the outcome of my vehicle. Nedbank is very unprofessional. Long holding times. Longer to get an assessor to view my vehicle and then I was advised that it would be 15 working days to resolve my claim. My accident happened on the 27th of May, with the service I'm receiving from Nedbank, my claim may only be finalized on the 23rd of June. This is ridiculous and unacceptable. I need to know the status of my vehicle. I cannot afford to be paying for an e-hailing service for the next month whilst Nedbank decides the fate of my vehicle and processes my claim. Do better, work more efficiently, resolve my claim!
