Citibank — credit card fees

Address:

400092

I was given a shoppers stop citibank credit card, which was told free for lifetime to me. However i started receiving messages for the payment, i tried calling up citi bank toll free numbers given in the message and on website, but none were reachable, i also tried making the payment, but the request was invalid... Now i have been receiving messages that my eligibility is being hampered / scores affected and so on. I have never used this card, and will not want to use it any more... So kindly assist me with the resolution by removing those charges (Annual maintenance) and closing my card immediately so that it does not affect my cibil scores
