Clientele policy cancellation

Clientele refuses to cancel a policy that they have put in place without me authorizing the debit order and debit order date. The lady who assisted me advised me that before the process is completed I will be contact by someone from their offices to to verify all my info and all documents will be sent to me via email after the call,but to my surprise clientele sent me documents stating the policy is in place and the debit order is set on the 25th of every month. I never gave the instruction to debit my account nor have I given them my banking which really upsets. Yesterday I sent numerous emails requesting for everything to be cancelled but they refuse to do that saying I must call their cancellations department which I refuse to do because they went behind my back and gave themselves the authority to go in into my account without my consent. There is nothing to talk about now because a conversation should have been held before the policy was activated.

I want the policy to be cancelled immediately.

Kindly assist I need Clientele to cancel this policy immediately.
