Unsatisfied with claim settlement ***

I have a home content insurance at Auto and General, so I lost my laundry last Sunday which is part of the cover I then reported it and got a case number. I called the claims department on Tuesday, 19th informing them about the loss of my clothes and the consultant I spoke with asked me if I have the receipts I said no as it has been a while having the items that were ****** so to my surprise today I got email from the consultant by the name of Veronique Naude informing me about the claim settlement which is far less that the amount I spent on the ****** items because there was no proof of payment(receipts).

Iam so upset the fact that when I signed in the cover there was no body who told me that every time I buy something that is covered I should keep the receipts and on top of that there is no way that one can keep the receipts of the clothes that were bought 3 or more years ago and when the customer puts in a claim then he/she gets asked for the receipts, how possible is that to have the receipts of the previous years.

Iam much concerned as some of the things that are insured in my house was bought way before I took out Auto and General insurance so it is like Iam wasting with my money for insuring my house content that doesn't have the receipts.

I need whoever is in charge for the claim to settle my claim as per the amount I spent on the items without having the receipts of 1 or 2 years ago, who keeps receipts for clothes over a year? Eve if I can keep them is that realistic to have such receipts over a period of time. Iam not happy with the claim settlement I got and it didn't acknowledge it until my query gets resolved as soon as possible.
