Refund for new customer's cancelled policy

Due to insufficient service with regards to changing details on policy holder that continued back and forth via telephonic correspondance and email from 29 November to 3 December, I cancelled our policy for Comprehensuve Car and Home insurance with Discovery Insure on 4 December. I phoned on 6 December to make sure policy was cancelled, just to find out it hadn't been cancelled on 4th of December. They corrected it and sent an email with cancellation in place. No correspondance up to date via telephone or email to let me know about the refund of my policy payment as I was a new client to Discovery Insure. This is unacceptable and would like to know when I will receive my refund please?
