Cancellation of my policy

I sent an email in September to cancel my policy and every time I call to find out what the status is I always get call back promised that never happen. You have made a deduction on my account again... I keep on getting sms's that I am owing claims and which I know I submitted a long time ago. I would like you to please cancel my policy with immediate effect and use the money deducted this month for that claim. I don't ever want anything to do with this company ad their false promises, changing terms and conditions and not letting customers know...I am not sure what I'm paying for...
