No forceful entry declined claim

I put in a claim for house breaking and my claim was declined because the was no signs of forceful entry. I have footages showing the guy gaining entry into my property and helping himself to my property. Insurance assessor claim the was no signs of forceful entry. The guy gained access through the roof and into my property and stole items worth over 30k and the bank says the was no sign of forceful entry. FNB short term insurance is the worst cover you can ever take. The management doesn't have the decency to call you and explain but quick to tell you they will be reviewing your cover as you're under insured. Too all those who think of taking up an insurance with FNB please be aware they are a bunch of useless and unprofessionally mannered bunch of no goods. I wish I never banked with them. if any bank out there reads this please find me look up Pule Silas Segabetla and make contact on any social platform you are able to find me on.
