Account debited twice

<p>I made a purchase and payment online via the credit card payment facility on the 26th of November and was debited immediately under reference "original online results". On the 29th of December, I was debited yet again for the same amount under the reference "supplement world". When I contactEd your call centre, I was told that this is my bank'statement problem as you've experienced similar problems in the past. After I contacted my bank, I contacted your agent again who later admitted that this is your problem. I still haven't been refunded my money! This is complete utter *******, it's unacceptable!</p>
