I was not cancelled immediately as I requested

My Wife cancelled her motor insurance immediately on the 15th September, she was sent the cancellation letter on the 22nd September stating that her insurance cancellation is effective from the 30th September. She had already taken out an insurance policy which was effective from the 15th September (the day she cancelled with dotsure). Now she was debited for those extra days from Dotsure and now she must also pay for those same days with the other Insurance provider.<br> <br> She sent an email to Michelle Thorpe and Venantia Ryan asking them to correct this, she did not receive a response. I am very disappointed at the fact that no one responded to this request.<br> <br> We want a refund for the days 16th September 2015 to 30th September 2015 as Insurance was cancelled effective immediately.
