Poor Communication, un-communicated deductions : Insurance policy

App**** for insurance online. Nedbank activate the policy before confirming the instalment and start date. They loaded a debit order for 3 instalments due to me requesting to pay on the 5th. No confirmation, no discussions, no notification they just deducting 3 instalments upfront. If you complain they tell you to read the policy properly, but you agree to the insurance before you receive the documents. Very Unprofessional Service!
