Paxi robbing its insurance and paying out its customers peanuts!

My parcel was affected by the KZN floods and in that parcel there were new clothes that I had bought for my son. Paxi requested that I give them the estimate value of my goods which I indicated that there were R1500. In the parcel was a new Kangol sweater, new pair of demin jeans and cosmetics. To my surprise, I did not receive the total value for my goods but a lousy R500. I want Paxi to refund me the full value of my goods or buy me the same clothing that I had in my parcel. I called their customer care service and did not get any help. It's obvious that when Paxi sent their claims to their insurance, they used the amounts we gave them and ****** us in return. I want my son's clothes back and will gladly refund them their R500 as it does not even cover even I item!
