Bad service

I had a break in the 9 Feb at my home. Today over 3 weeks later I received a mail that say my claim of R17554.50 they are only paying out R4432.67. They say that my one laptop of R6999 wil be settled for R4499 and the other of R9999 will be R5299. And then according to them I'm under insured by almost 50%.

I understaand that I'm under insured, do not beleived by that much, but ok.
