Insurance claim not fulfilled

From 2019 in February I placed a claim with Standard bank concerning a break in at my house. The damage to my property is substantial and I won't be able to fix it. They approved my claim but after the doors and a security appointed to look after the property to prevent further damage they stopped. They said they are going to send an assessor to asses the damage. They appointed Mr Khan in the aasurrance to deal with my complaint. Nothing has been done up till today. I have started now to repair my house myself. I am a customer with standard Bank for over a year. I never thought that when I am in need of them they will abandon me. It's sad and I think very unfair.
