Cancelation of Policy

I requested for my policy to be cancelled on the 1st of October 2015 with all the required documents. I receive a email from Lebogang that he received all the documents and he he will send the info to the policy administrators. On the 2nd and 6th of October I followed up with no response. I phoned 2 times after that of which I was told that the administrator did not cancel my policy. Lebogang put me in contact with the administrator which told that they did not receive a cancellation letter from the bank. They pro missed to copy me in all the correspondence with the bank. that did not happen also. Since then my bank account was debited with the amount each month. I completed the policy cancellation form and attached all the required documentation as requested. I can't understand how this is my responsibility to follow up directly with the administrator as beterlife is the agent. Furthermore if there is any additional information required to cancel the policy this should be requested on the policy cancellation form. If all the required documentation is submitted with policy cancellation from how can it take 6 months to cancel my policy. Please refund me for each month.
