Very poor service

In September 2019 we claimed for a burst geyser that had also damaged the ceiling and laminated floor below. From the start, the workmanship has been problematic. The finishing of the replacement ceiling was poor and had to be redone. The pipes replaced to the geyser were not fastened and when hot water was used they would swing back and forth in the ceiling hammering on the trusses. There was another banging noise in the pipes that had something to do with water pressure. While most of this has been fixed over 2019 and 2020, the geyser blanket has not been replaced, I have not been paid out for the damaged flooring, and there is still a whining in the pipes when hot water is used. This has not been addressed and they now want this assessed as a separate claim even though it stems from the replacement of the geyser. I don't see why I should be penalised for their poor quality of repairs.
