Unnecessary actions by Miway folowing a claim

after having no electricity for almost 3 days, when the electricity did come on we were getting 430 volts through our mains. due to this numerous appliances were damaged. We put in a claim with Miway for the electrical appliances that had been damaged. I phoned the call centre to register the claim, who asked me if I had surge cover or if it had been offered to me at the time of taking the policy to which i rep**** that i did not remember, and was told that they would listen to the recording, which i understood. I then had calls from the Assessors who came to assess the damage, but had to come back, as we still had no power - the Assessors were extremely helpful and pleasant all the time, and they returned the next day when power had been restored. However, I then got a call from a lady who said she would be handling the claim going forward and would need to meet with me at my home, necessitated me taking time off work. When she arrived, she asked dozens of questions (like an inquisition) and took photos throughout my house and cottage (all the time "recording_the conversation" ) After 1 1/2 hours of my time, she played the recording of my initial conversation when taking the policy, showing that I had refused the cover for surge protection, not taking in the fact that the agent had influenced me negatively, stating that "most people dont take the cover" , and pushing me to leave it off. While i fully understand that I refused the cover, regardless of his influence, , I fail to understand why I had not simply been advised of this at the outset, and that my time was wasted, and i felt like I was being treated like a ******** for having the audacity to claim. I will definitely be looking elsewhere for insurance
