Barclays Credit Card Complaint

Barclays Credit card department,

Cash advance fee Ohio

I authorized a credit card purchase of $500.00 through - using my BarClayCard on - -, 2015. I now see that they charged me interest and a cash advance fee for the purchase. This was not a cash advance fee. I believe that because I am using their special promotion of 0 % interest for 2 years, they are trying to get some kind of money out of me. I did not authorize a cash advance on my card and nor would I. They told me I needed to speak to -, which I did on a - call with Barclaycard. - clearly stated that they charged my card as a credit, not cash advance. I believe they should refund my almost $50.00 worth of fees for this transaction as they can not produce a disclosure stating I would be charged a cash advance fee for this transaction.
