payment came off 2 times for my bond

I asked the man at enquiries (the manager) to change the date of the direct debit to the 6th of every month. I signed the forms and they said it had been activated on the system.<br> <br> Then they took off 2 debits. I need the money and am still awaiting them to refund the 2nd payment.<br> <br> Please call me asap to discuss.
