Bad service and being taken for a ride

I lodged a claim for a geyser burst and their plumber replaced it but the following day there's a leakage through my ceiling and when I called them again and they came to say there is a rusted pipe to to the geyser which is separate claim all together and I will be liable for another excess so I am going to pay 2 excesses for the same problem I don't think I want keep my policy with FNB brokers their suppliers are ametures and he was rude to me and to top it all my ceiling is damaged as well, they could have fixed correctly first time around.
