Double excess fee on a single water leak claim

I've never had such a horrible service experience in my entire life. I have logged a claim with *** with miway for the invisible hot water system leakage in my house on the 11th November 2023. And to date I still have to follow up with the handler, and as if that's not enough I'm expected to pay double excess fee because the leak detector/ passes plumber has detected multiple leakages along the line... I feel this is just money ******ion on top of the premiums we are paying. I feel like I don't have insurance at all at this point 🤔💭
