Mistreated Client

I have been so patient with FNB and their short term insurance. Earlier in the month I logged a claim with them for my damaged device, and they gladly rejected my claim. I disputed the outcome and they were very stern about the decision they had taken. I then went and replaced my phone from my own pocket. I immediately called them as soon I started using my brand new device, I asked them what do they need me to do to update my cover. I was told to send POP or an Invoice from the store. The store emailed me my invoice and I have a physical one with one, I forwarded one that was sent to my emails, and I got treated like I am *****. I rep**** to their email by asking them if they want a selfie of me and the receipt for them to update my details? How is it that a client is being treated like this? Are these your values as a business? To ill-treat your clients? I am requesting to update my policy, why make it difficult for me?

Utterly disgusted by your service.
