Do they honor any claims?

Besides the last 2 claims they denied here is the latest. I have a roof leak in 2 places and found out about it after the heavy rain a little while ago, so naturally you call your insurance because this is why you pay for it.

14th June - I called on 14th of June to log a claim, the administrator told me that someone will contact me ( i have the name) the next day to begin the process. 17th June - I followed up on the as nobody called me yet so i can log my claim. 20th June - I was called on the and the claim was logged. 21st June - The assessor came out and did the assessment on the damage 24th June - Sent a follow up and no response received. 27th June - i called in at 9am, i was told by 11am i would have a response. I called again at 1pm and a gentleman assisted me and basically told me my claim was denied. The basis of the denial was because your roof must be sealed? I mean how should anyone know this? I mean the whole reason for taking out insurance is because you are paying for the unknown. I don't know ANYBODY that has checked their roof to make sure its sealed before taking insurance? Did you OOBA tell me i need to do this? Besides the fact that they have no customer service, they find every single way to not pay you.
