Poor Service for a claim

I am trying to claim for household contents after damage to our appliances because of a power surge. I am getting the worst treatment ever, like I have never paid for this insurance. There is no communication and everyone is passing the buck. I will never use Auto and General ever again. It seems they think I will just give up and replace the appliances at my own cost. I have claimed from other insurance providers and have received much better treatment. I have had to incur costs because of the delay in the processing of the claim. They don't give updates, I have to spend money calling them only to get non-committal responses.
