American Express India — unlawful debt before the renewal of the card

Address:

Kolkata, West Bengal, 700078

At the time of issuance of the jet privilege platinum gold card in 12-13, it was informed that one time amounting rs 10, 000 will be charged and as against, bank will provide 20k jp miles, 1 complimentary tickets and airport lounge access and american express had provided only 20k jp miles.
At the time of 2nd renewal, again amounting rs 10k +taxes had been debited, i have asked the customer care to send a corrected invoices but they have blocked the card.
Now, i am getting a calls from the bank to clear the dues.
Please note, it was not the expenses, which i have incurred and not paid and before the renewal, the card had been blocked, hence debiting rs 10, 000+ tax cannot arise.
Please resolve the issue and confirm
