IDFC First Bank — Cancel / deactivate my emi card immediately

Mr Naresh, please let me know whether they did resolved the issue, because recently I hv purchased AC through their emi method and got completed with noc but without my prior concern they did sent a easy emi card to home, when I checked with merchant where I purchased their response was not so acceptable, saying that it will be deducted on a yearly basis of rs 99 as service charges. I couldn't understand why idfc sent a emi card without our consent also amount deduction n all. So it would be helpful for me to do the same to cancel it before getting any deductions, since they tied up with our banking accounts.
