Claim declined for an invalid reason. No communication

Completely dissatisfied with ooba building insurance. Pathetic if I must say, you can't get hold of people and let me not speak about the assessors they appoint who are delayed and are trained not to give proper feedback so that a claim is approved. I am a new home owner I bad the best bond originator from ooba so I thought that ooba was an excellent company since the bond originator was phenomenal. My house was registered in Feb 2022, I moved in 12 Feb to realize there is water coming down on the walls, 13 Feb as well the same problem. I called the insurance company and told the guy I just bought this house and to my dismay there I waster leaks. He noted this as urgent but the assessor only arrived Saturday. Today on the 24 I get an email, claim rejected because of loss of, destruction or damage to any property whatsoever as a result of lack of maintenance of the Dwelling, or any loss or expense whatsoever resulting or arising therefrom;

3.6 loss or damage caused by or attributable to defective design, specification, construction or material;

3.7 loss or damage caused by any gradually operating circumstances;

3.16 Loss or damage caused by wear and tear, depreciation, electrical or mechanical breakdown, rust, corrosion, mildew, moth, vermin, insects, your own domestic pets, ******s or any gradually operating cause, process of dyeing, cleaning or renovating, the action of light or atmospheric conditions. Are you kidding me right now I just bought the house I have not lived here for even a year it's 5 weeks! And you say I am to blame really :( you state I must pay to repair. I have no home! Water is running down the walls. I keep calling and I get pushed from one person to the next. Please ooba this needs to be fixed asap. I am homeless right now even though I am homeowner for 5 whole weeks. So sad that a company who is supposed to have their customers best interest at heart is so heartless saying it's negligence really? I would like this matter resolved please. I am stressed to the max here I have two small sons that have no home. My anxiety is on 100 was sent home early from work because I was crying whole day asking myself where do we stay where do I get money to fix this roof.The rain yesterday that was bad in PMB just added to the pain. Please help ooba insurance.
