Budget insurance: terrible response to claims

I took a business insurance with Budget insurance in February and unfortunately had an incident on Friday where my laptop was ******. Now 4 days later and after numerous calls to follow up on my claim Budget has come up with additional requirements and demands and is giving me no indication as to how my claim will be handled. I feel treated like the ******** and am questioned whether my laptop was insured in the first place,and how it is that I have a claim so soon after the insurance was taken. I still do not know how the claim will be resolved and am given no clear timeline. Budget was very quick to sign my company up for insurance and take our premiums every month but now that it has come to them doing their part they are non responsive and are using delay tactics. I have never experienced such treatment with other insurance companies before.
