Digusting Service from service provider

I am insured with Nedbank insurance and my house was damaged from the recent hail storm on the 16th of November 2015, I called in to lodge a claim and assessors came on the 18th to review the damages and appointed contractor Batho Pele to do the repairs, who then appointed a sub-contractor, and that was the beginning of my nightmare, the sub-contractors appointed another service provider to come and do the job. I have been calling and following up with the assessor as the procedure was lengthy and no one had the decency to provide me with any updates he assessor always refers me back to the contractors who just gave me empty promises. I thought insurance was suppose to give me a peace of mind and value for money as I paid my premiums every month but on the contrary I have been running around during my working hours to ensure that my house is fixed, the service providers came to do part of the job and I was shocked at the quality of their work, and it's not complete, Can someone see to this matter before I approach the Ombudsman!!!
