Outsurance deducting twice from my account

I changed my banking details with Outsurance and the have deducted the money from my new bank account on the 2 March however I now received a letter as well as an sis that my debit order was returned!!! This is not correct as I can see it went through. Outsurance deducted from my current as well as my old bank account.<br> <br> This is extremely worrying as I will now be liable for bank charges.....?.....<br> <br> J Wasserman<br> [Email Removed]<br> ***
