sh*t service received

I had an incident last week of people who came to take rubble in the house. I realised the following morning that my coffee machine, which was still in the box was missing. I submitted the claim to the insurance. A picture of a machine or invoice is needed which I don't have. I called the supplier; they want a serial number for them to give me an invoice which I don't have. The sad thing is, when we take insurance, no one comes to your house to check what you have and don't have. No serial numbers are requested. Most of the time, the invoices are thrown away because you don't anticipate losing your belonging. Having insurance is just a ****. Now, the agent informed me that no claim will be processed without a picture or invoice, i have none of those. I will not go around forging an invoice or requesting false invoices. Cancel this claim and cancel my all my policies with outsurance. It is better to stay without insurance.
