On Friday 02/08/19 I took out motors trade insurance. I used a company called Peacock Insurance Services. I paid my £300 deposit and was told thats it set up.I then received a letter today 06/08/19 dated 05/08/19 from a company called Policy Plan saying my insurance was cancelled with no explanation.I immediately called Peacock Insurance and they said Policy Plan have wrote to them saying I got a question wrong in my application so have cancelled due to misrepresentation. When I asked for my money back they have told me Policy Plan are refusing to give me any of my £300 back.I am furious. Not once was I emailed or posted any terms and conditions from either company telling me of any cancellation fees. This surely cannot be legal.The question I got wrong was they asked me if I used to be a director of a company. As it was over 5 years ago I said no. Its not even a major thing and cant understand why this would even prompt cancellation.I have wrote to Peacock and Policy Plan. Only Peacock have replied today saying they need to wait and see what Policy Plan says even though I only dealt with Peacock. They have said it can take up to 8 weeks for a reply. I cant wait that long for my money back.Any help would be appreciated.Thanks
