Barclays Time Credit Card. — priority circle

Barclays card has billed me for Rs. 6000, 00 for their promotional offers which I don't need.
I am low income & honest guy and spent according to my pocket.
This is not fair that these people are doing. They have unnecessarily billed for their promotionla offer which I do not need.
I will use my card according to my need and pocket not unnecessarily.
I am very upset after it came to my knowledge.
I have called the Bank many times since Oct08 but did'nt received any possitive response and any reference no.
Please help me to get this transaction reversed.
i am unable to pay this amount thnking u
