Double Debit order after agreeing to reverse the payment.

I contacted them on Thursday to reverse payment of premium paid to Outsurance on 26 March as my previous insurance company debited my account. I was under the impression that the insurance will be cancelled. I was told it will take a few days. Then another debit order took place on 30 March, thus instead of reversing the payment, another payment went through. Go through your recordings, where I stated the policy needs only to be made active the end of April, which the consultant agreed to.
