OnePlan Insurance review: Policy cancellation when I did not even sign up for it

a Customer service agent phoned me for a quote and gave all my details. He then asked for my bank details which I did not want to give. a Manager was called to explain that it does not finalize the policy it is only to get the documents to the underwriters, which hesitantly I gave. Waited for 5 days no documents. Phoned in and was advised that policy documents on the way. Still nothing. Went online to ask what is happening with the policy and apparently incorrect email address which I gave. As I told the Customer Care person, Me and my husband would review the policy before we accept. The 28 August I mailed in to cancel as we have decided to go with my husband company policy. This was in the 7 day cooling off period. An Cancellation agent phoned me today to tell me a debit order will be taken off my account as they need a months notice. I never agreed to this and was horrified at the way the Cancellation person spoke to me and laughed over the phone. This is such bad service. I have never experienced such terrible service. I was tricked into giving my bank details as the manager assured me that I have to authorize the debit order details via sms and never did. I will not be liable for this debit order and want it stopped. Policy no [protected]
