Pathetic service and Poor communication, don't do what they say the will do!

I contacted Ooba Home Insurance 5 months ago about a claim, eventually sent a assessor, waited forever for them to come back to me with a rejection letter. The reasons for rejection were invalid. No correspondence from them at this point. Told me to find a certified assessor if I want to escalate the claim but have not pointed me in a direction to find one.
