Money being deducted for deliveries that were never made.

I recently had money debited to my young daughter's bank account for a Mr Delivery order that was not mine (I have never used Mr Delivery). It was not a small amount and when I logged a query with them as to where this delivery had been sent I was given the run around. The bank account in question is not used very often and the card had been used for the 1st time in about a year. The card is also so faded that you can hardly see the numbers. Mr D did reply to me asking for the amount and the last 4 digits which I gave them. they then requested a copy of my bank statement. which I was not prepared to give them seeing that money had already been removed from my account. Rather than contacting me to discuss they just closed the call: "Please note that we are unable to investigate your issue due to lack of information." They had the information just not the bank statement.

Why am I required give a copy of my bank statement in order for them to confirm that the money was deducted from her account? I don't even know where they got the information from in the 1st place.

It seems to me that they are happy with the fact that they are getting money via *****ulent transactions and are making it difficult for the victims of this *****.
