Debit Order re submission still awaiting confirmation

I called Outsurance in the middle of last (March) to have my premium resubmitted for the 25th April 2019. I even spoke to an agent and also submitted my request via the app. I received notification that my premium will be resubmitted on the 10th April this debit order for the 10th April needs be cancelled as it will reflect as a failed debit order on my account which affects me negatively. No confirmation has been received from outsourance confirming my re submission for my premium to go off on the 25th April. If Outsurance does a debit order on the 10th April 2019 i will hold Outsurance liable for the failed debit order charges. i Need this sorted out.
