Useless Claims process

I have a home loan with Standard Bank and have been trying to sort out a claim with regards to my property since last year November. Although the bank has sent out an assessor twice they have not managed to take it any further than that. Damage was caused to my security gate, camera and electric fencing when lightning struck a tree next to our wall. After numerous phone calls and emails I had to get the issues sorted on my own account as it was obviously a security risk especially over December. Since then I have kept at it trying to claim back the money I spent, but Standard bank is simply ignoring the claims and requests. The email they supply online and via phone is inactive and bounces back ********** the claims line is always unavailable due to high call volumes and they simply do not respond to emails sent to complaints. I have tried every number and email address I could find and sill have not received any feedback from the bank.
