Cancellation of Policy not done

Hi<br> <br> I sent a cancellation letter on the 18th August 2015 to cartrack (i have my email proof and members who read my email) in my possesion. They deducted the 26 Aug 2015 when i phoned them they said it was because the cancellation period is 21 working days. I accepted that. On the 26 Sept they deducted again. I phoned them again and they has all kinds of stories that my policy was emailed to the wrong email address for cancellation but that they had forward it to the cancellation dept on the 19th August. They told me it will took 7 to 14 days to refund me. I am still waiting for the refund. They didnt even email me like they said they would do. I think this is very bad after service and that they are playing for time as it is getting again to the next period for deduction . Then i have to redo this whole process again.
