Terrible Service from Standard Bank home insurance

I had my roof damaged again in the storm for 3 weeks now, no-one fixed it as yet. A few months back standard bank had a contractor to fix it, its leaking same place again, all the evidence is there thats its the same place, they did not do the job properly the first time. The first assessor even picked that up, Standard bank and the contractor refusing to take ownership. I am going back and fourth. This as been the worst experience of a service. I also have to wait like even over 30minutes to speak to the callcentre, the communication from them is even poor. Its actually sad the poor service that i am receiving, the weather is terrible and things will just get worst and they not intrested
