Insurance claim delay. Incompitent service

Good day I have a commercial insurance policy with Standard Bank under the policy number SIL32934COM. Two weeks ago I lodged a claim for a machinery that I have covered under the policy, I was asked to send a damage report along, I did the report myself explaining the damage of the machine because I didn't know that it was supposed to be done by a technician. The claim was not responded to until I asked my banker to follow up who then was told that they can't process the claim because it is missing a damage report. The bank then arranged to have an assessor Lourens come to assess the machinery, the assessor came on Monday 28th October as agreed but he came at 13:30 instead of the agreed time of 10 am, he said he was delayed by the guy that he previously went to. He got to the surgery(where the machinery is located) and took pictures of the machinery and also noted down when the machinery got damaged and what happened. I was surprised because I thought he was there to right a report of damage after his assessment, he then told me that a technician needs to write a report. I asked my lawyer for advice and I was told that the assessor was supposed to write the report, I called the assessment company and they denied that it was their duty. I then contacted the bank explaining to them that there are no technicians who can write a report for me as most of them are independent and not under any company, if I need a technician who will have a letter head I'll have to get them from other provinces and that would cost me because they charge per kilometer, assessment and writing the report. The manager then suggested that I give her and the person responsible for my claim Stezron the number of the technician I use in my province. I did that but the technician has still not been contacted till today and Stezron does not, not even once has he called me to update me about my claim. I've been out of business for a while because of the broken machinery and the fact that Stezron and the bank are delaying the process of the claim is unacceptable. I want this fixed as soon as possible. My claim number is SIL32934COM/1. Hoping to get the service I pay for.
