Nedbank homeowners insurance dragging their feet with fixing damages on my house.

On the 12th of December my boundary wall fell due to storm and my windows broke, washing line steel pipes were destroyed as well and the structure of the house also got damaged and I put in a claim (C***) a lady by the name of Ntlotliseng Lebitsa was assigned to handle my claim, so from the day the well fell due to storm damage till yesterday no windows were installed in my house until I installed them myself, If this was treated as an emergency the least Nedbank could have done was to install windows in my house, so for 6 days the were no windows in my child bedroom and my bathroom so who is suppose to be liable for the damages caused by the rain and wind? Every time I must phone nedbank trying to find out what is the status of my claim, they sent people to do the assessment on the wall, the wall is still not up instead they put IBR sheets as a temporary measure, what I want to know from nedbank homeowners insurance is are they ever going to fix the damages on my house? the lady handling my claim says they are waiting for the final report from the assessor Lesego Kgopane but when spoke to her she says to me she is done on her side with the assessment on her side, so why are they wasting my time.
