Cancellation

On 04/03/2015 I called in to the call center to cancel my policy I was told to submit a written notice and a consultant would call me back I asked to be transfered to the cancellation department I was told I cant recieve that as they would call me back which they never did, instead they been trying to debit my account, I got uncomfortable when no one could tell me when I would reciece cards that I paid for, on the 24/03/2015 I sent a follow up email I got an automated response and still no call
