Still getting billed for get more after a over year cancelled

Hi I'm writing to query the billing error on my contract for the number ********** . I had cancelled Get more on my contract in July 2016 and was informed that the cancellation will only take effect from Aug 2016. Since August 2016 until today I am still getting for get more. I've called and queried this and too many times I've been told to call at a different time and times I was told I'd get a call back. None of this ever happened. I still can't get through to you guys. Calling or sending a query on your website does not help. Why do I have to complain on HelloPeter to get a response from you???? Please refund me all the monies you stole from my bank account
