Explicit instructions ignored

Yesterday I received a call from Vuyolwethu Malamlela to give me a quotation for motor vehicle insurance. I was happy with the quotation so I called Midway to cancel my policy. Miway offered to review my policy and get back to me today(30 September 2015) I then instructed Vuyo to make my debit order effective on 01 November 2015 so as to avoid being double debited seeing that I hadn't cancelled my policy with Midway. I arranged for Vuyo to call me on 30 September 2015 at approximately 14:20 to confirm my decision. After speaking to Midway I was convinced not to cancel my policy with them. I waited for Vuyo to call me as arranged but when she failed to do so I called Budget Insurance to cancel their quotation. I was informed that they will cancel my policy however, the debit order had already been submitted. This information was most distressing because it went against my explicit instructions for my debit order to be effective only on 01 November 2015. The policy with Budget was processed even before my existing policy was cancelled. Even though I was promised that I will be reimbursed, the 7 day waiting period inconveniences me financially. I am so glad I cancelled Budget...
