FNB bad service

I have a house content insurance with FNB and my Homeloan is with them too…I opened a claim in 2022 in Nov/Dec and FNB sent the company to fix which they did. Two weeks later same problem mind you I pay for excess. I informed FNB that inspite that the problem has been fixed there is a big noise that I hear whenever I open the hot water. They ignored my feedback. Now my geyser is leaking again and I being asked to put another claim no ways… I have two claims already for the same problem.
