Policy cancellation

My policy has been cancelled due to 2 consecutive months of non-payment, I called the company on the 2nd of January and advised them that they didn't debit my account on the 1st as agreed and also advised them that their debit isn't going through on the 1st of each month. I then asked for the banking details so that I can make a payment and was I advised that they can make an arrangement for next Thursday the 8th and a double payment will be done. To my surprise I got a mail telling my policy is cancelled and I called again and I was told it has been cancelled, and I need to be transferred to sales department a get a new quote. Can i get clarity of how is it cancelled even though arrangements were done Contact number: ***
