No Feedback or Assistance with Insurance Claim

We raised a claim with Nedbank Insurance on 14th May, following a break in, the whole process has been extremely time consuming and stressful. The call centre continuously cuts calls and takes 21 minutes to process the claim whilst they have you holding on the line. We appointed the repairer ourselves as their process takes too long and our home was not secure. Their assessor went out to site on 15th May and since then we received no feedback. I contacted Nedbank Insurance on 19th May and they told me that the assessor had not put in his report, that they would follow up with him and get back to me, I then received a call from the assessor Cornell Erasmus who asked me why I was complaining about him, I took exception to his tone and to the question and asked when he was going to submit his report, he made various excuses as to why he hadn't done so, asked me to mail him the Contractors invoice and said that he would then forward me the report and forms. I mailed him the invoice, I have still not received the report or form, the Call Centre is a waste of time and when I messaged Mr Erasmus he messaged back to say that his wife went into labour yesterday! Unprofessional!!!!
