Disappointed in Nedbank Insurance Dept.

I put in a claim for a burst pipe and had to get my own supplier. I then submitted all the documents to Nedbank on the 2nd February. I followed up and was told they had not received all the attachments. So i resent. I did emails asking if all documents had been received. I got no response. I phoned. Then they had to check. I resent. Sent more emails. I was then told it takes 2-3 days to process payments. Still nothing. i followed up again. I was retrenched so was relying on this income coming in. I received a sms on the 26 Feb to say payment had been approved and will be in my account within 72 hours. Well today is the 09 March and I still have not received it. My account is in overdraft cause of the delay in them not paying. Are they going to compensate me for the loss of income and having to pay interest?
