Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Cash advance fee Ohio

I opened a checking account funded with my Barclays Wyndham credit card for $10000.00, and they posted the transaction as a cash advance and charged me a $500.00 cash advance fee. The charge should NEVER have gone through as my cash advance limit was limited to $6000.00. This is a security issue on their part letting transactions go through that are higher than the stated limits on the card.
