Feels like we got ****** twice!

It was with great excitement that we moved into our new home but unfortunately 6 weeks in there were people who decided to pay a visit while we were away and take what we worked so hard to earn over time. We have been fortunate enough to not need to claim for such an event in our time but trusted that we made the correct decision with our insurance provider. Unfortunately when it came to make the claim my requests went unanswered. After two days of not getting a response I chose to call in myself. Finally the claim was submitted after using more than an hour of my own airtime. Wait two weeks for the assigned assessor to finally come to our residence in order to interview us regarding the incident. So much time in fact had passed that he had to rely on photographs that we took on the day. Under the pretense of good advice the assessor went through our house to take inventory of our possessions in order for us to have a better understanding of what needs to be covered. The fact came out that this exercise was to inflate the "value" of our belongings in order to later say that we were in fact under-insured as we did not account for items such as groceries in our calculation. This total was never communicated to us until the bomb burst three days before the one month anniversary of the break-in. Now, due to an inflated estimation, they want to refuse 35% of the claim for a claim amount that is roughly 15% of the amount that cover was chosen for. It is not that I have a misunderstanding of how the process should work and thus have unobtainable expectations as my standards have been set by one of their competitors with whom my buildings insurance is covered. Not only did the competitor phone me within an hour of submitting my claim which speaks to better customer service they provided me with an accurate estimate of the replacement value for my property to ensure that I have the correct cover from day one instead of sending a professional assessor after a claim to blow holes in my "uninformed" estimate that was accepted with open arms.
