Auto & General please do what you promised

I am an 84 year old woman and a customer for more than decade. My house was burgled twice once in March and again in April. Auto and General is most unhelpful and the only reason I have not left them is havin little access to the internet. I Ave put in my claim provided them with what I could my question is how do they expect me to prove stuff I have acquired over twenty years ago please show me who keeps receipt or boxes that long. The assessor has been at my house and witnessed the damage of the second burglary and still I get no help. Kindly note that they deduct their money every month. I called today from a borrowed cellphone spent 40 in airtime and nobody calls back. I sent numerous emails to my claims processor and still nothing. What must I do next.
