Not very happy at this moment

I lost my washing machine due to accidental damages. I submitted a claim. The assessor came and submitted the report to Discovery Insure. The problem now, i am stuck without a washing machine. I have been sending emails, asking if I could please replace the machine out of my pocket and send the invoice to them and whenever the claim is Authorized and whatever the outcome is, they can refund me if it is approved or if it is not approved then I do at least have a washing machine. All I get is once the validations are complete I will be informed and available options and sms's saying my claim has be assigned to another consultant and in the meantime I am the frustrated one because I cant just replace my washing machine and send the invoice to them as proof that I replaced it. What if I my claim is not approved then it was time wasted waiting on feedback? This being my first ever insurance claim in my life and having this experience. If I was a person constantly claiming I would understand but I don't. I do understand claims take time to Authorize, but not allowing a client to replace a item on their own and sending proof that it was replaced is not acceptable.
