Barclaycard Priority Circle — Please help me out in cancellation of the membership of Barclaycard Priority Circle and the Barclaycard

Hi,
I am suffering from Barclaycard Priority Circle . Actually what happened, I received a call from Barclay from the number[protected] on 27 Sep 2008 and it was told to me that I have been selected in the lucky draw for the following things and that are absolutely free means I will be charged nothing:

1) A travel bag worth rupees 2, 000/-

2) Travel package

3) Cash back on shopping

The main point is that I asked again & again during the conversation regarding the charges/fee if any but it was told to me that there is no charges/fee. You have been selected in lucky draw so we want to give these things to you absolutely free so I trust on the same. In the entire conversation, they never told me about the registration fee of Barclaycard Priority Circle that 6, 000/- which I have come to know later when I received my Barclaycard E-statement. Now according to Barclaycard E-statement total due at my end is: 7253.65 (Including interest + Service Tax).

So I am really helpless now. Please suggest me how I can come out of it?

Regards,
Rajeev Kumar
