Disgruntled FNB Homeloan client

I bought a house through FNB Homeloans in the year 2022. The bond was approved and I moved into the property on 29 April 2022. Upon moving in I've have experience endless challenges, submitting claims where all it of it was rejected. After I moved in the neighbor advised me that the parameter wall was about to fall over because of the trees pushing against the wall. It was about 11 huge trees pushing against the wall. The challenge that I am facing is that this house was not bought voetstoots. That damaged wall is very visible to the naked eye and I am surprised that I was not warned by the bank that this is the condition of the parameter walls and I will have to fix it ASAP. The front wall on the property is also badly damaged with a crack right across and next best when it falls over it will be due to maintenance. Every claim I have ever submitted to FNB was rejected due to maintenance except my gate motor. So if I live in a house for only 3 years, why are my claims rejected due to maintenance and on such huge items or damages caused by weather conditions, am I liable for all those damages. The damages I have to repair is so costly I can hardly breath. I reached out to the CEO of FNB Insure @Lee Bromfield and he advised that he will have the matter looked into by the COO. Today, I received 2 calls both on confirmations of rejections of the claims The worst part of it is, I received 2 sms' from FNB Insurance on the 25th of April after the assessment was done stating. "We have appointed a service provider on your claim" time 13:07 and 13:08". 5 days later I receive a call that the claim was rejected. How to you appoint a service provider and than reject the claim 5 days later? Did they realize the extent of the damage and how costly it will be and decided to reject the claim 5 days later after appointing a service provider?
