I bought some travel insurance from the post office yesterday. As there wasn't enough space for my third daughter on the sheet provided, I had to write her name on a seperate one. I paid £50 which is correct for 2 adults and 3 children but i noticed last night that her policy number is different to ours and, also, i haven't been given the policy for this particular number. Is there anything I can do? Can the post-office scrap my first application and start again?
