No I/D, cannot pay your account

I was at your Cradelstone branch and wanted to pay a Markham account. I had the statement / tax invoice with the account number on. Sunday 6 December. The two men behind the till said that they could not accept payment without the card or I/d of the person. Why ? Surely your computer can look up the account by the number. I had to call the person and ask for the I./d number, go back to Markhams and then they accepted my cash.<br> <br> Is this the case or are these people working there *********** ? Not impressed with your service.
