MIWAY - CALM BEFORE THE STORM - WHAT A LIE

My house burnt down on 10th November, and I WAS insured with Miway. I lost almost everything in the fire. Miway arranged to collect all contents and send to a storage company to be cleaned etc. Miway also ensured that me and my family were provided with alternative accommodation. They have now rejected the claim after 3 weeks of the incident due to a non disclosure of claims dating back 2-3 years ago and cancelled my insurance (also promising to refund me with my premiums NOT)! What person would recall a loss after 2 years ago?? Why did Miway not do a background check at the time and inform me / that the could be an issue if something had to have happened? My premiums would have possibly increased slightly, but that would not have been an issue at all, as I have had uninterrupted insurance for over 21 years, and never had issues. I have requested that my contents be returned to me, however, the Storage co has requested payment from ME prior to the delivery occurring? The alternative accommodation requests payment also from ME? I did suggest getting a cheaper monthly rental earlier? The rejection letter was only sent to me on Friday 11th December. THANKS MIWAY, I AM NOW HOMELESS
