Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Transaction issue New York

Barclaycard credit card, issued by Barclays Bank Delaware, continuously flags my card for fraud requiring that i contact and spend hours on the phone. After resolving the matter at considerable expense of time on a call to them, and after being reassured that the hold has been removed, I try again to use the card at the same merchant and again the charge is denied and flagged for fraud. Each time that I call I am told that there is nothing that they can do, and more importantly, they refuse to tell me the exact cause for being flagged. At this point the items that were to be purchased for - will not be received on time. Even after escalating to the resolution manager, both times, nothing is resolved.
