Citibank — citibank' suraksha credit shield

A certain amount is being automatically debited to my Citibank Credit card under the head Suraksha Credit Shield. Till date Citi bank is not providing any details of the policy No. and the package offered. On telephonic conversation they are blank on how much Premium they have collected in my account and how long I have to pay the premium .. should I not get the hard copy of the policy ?... On telling them to discontinue charging the amount to the card, they conveniently say, after a month it will be discontinued... so what about the money paid till date ?? I wish my grievances be attended to .
