Request for itemised billing for prepaid

i am struggling to get itemised billing of a prepaid sim card for this number ***, as calls were made on the 22 august 2015 to block a bank account, now the bank will not give a refund if we do not supply them with the itemised billing for 22 August 2015, we tried vodashop and call centre and even registered an account online. may somebody please help with the itemised billing so that the bank can refund us all the money that we were de*****ed.
