Bad Building Insurance service from FNB

FNB home building insurance is the slowest and has terrible service. I had a gesyer burst on the 25th June 2022 at 11 pm when I arrived home and was welcomed with a flooded house. I called FNB regarding this matter at 12 am and only sent out a plumber at 9 am. The plumber only identified the matter as a broken vacuum breaker and, after more than a week, realized that the geyser actually burst and had to be relocated outside. FNB does not keep in touch regarding the assessment of the damage of the property, I had to call time and time again and now it has been 3 weeks since the incident occurred and still no final assessment has been concluded. I am tired of calling and waiting for no feedback of the assessment or feedback regarding the repairing for the building content that needs to be fixed. what matter am I still waiting for!!!!!!!
