Bad service Claims - house content, all risk,build

I have reported a claim on Wednesday 21 October 2015 on my I phone 5S and after numerous calls and little response from quicksure they wanted to pay out 6100 fir my I phone that's replacement value is 8500. My policy value was amended by quicksure due to my claim done in march on my I phone 5 and then my insured value was 10600 but due to the replacement done by quicksure via cellphone boutique. I originally had a quote for 10500 on a I phone 6 but could not get stock on a I phone 5s and quicksure decided to use cell boutique and the replacement value then was 7100 and they decided to change my insured value to the same value. Now who should take the blame for quicksures mistakes the customer, no way. I have also registered a building claim and an accidental claim for my dvd player. The bluiding claim there is numerous excuses and still not dealt with correctly for they only want to pay the pipe leak inside the wall and 3 tiles estimated and not the water damage or replacement of tiles and repairs. The dvd player they would have aaranges pick up but never occurred. They have a voice prompt that all calls are recorded and I demand this to be recalled and also have all the proof
