Cancellation taking too long

Discovery has always been quick to call back and answer emails. Now that I want to cancel my insurance, it seems they are dragging their heels!! On 28th October I emailed and asked how long it would take for a cancellation to take place – I was told it can be done immediately (ref - ********** 487). On 23rd November I emailed to cancel my policy and have my November debit order only debit for 5 days up until the end of the month as my new insurer would cover me from the 1st December. I was told my query would be sent to the cancellation department (ref – ********** 898). Nothing came of it. On 26th November I was debited for the full amount of the insurance – clearly my emails have fallen on deaf ears. Today, 27th November I called to find out how long my reimbur*****t would take but I was put on hold for longer than my airtime could survive. Now I am asking: 1. Please call me so that I can find out what’s happening and when I will get my money back. 2. When will my policy be cancelled? 3. When will Discovery arrange for my DQ tracker to be removed?
