ICICI Bank — Unintended transaction

Address:

110017

Respected sir'
It is to submit that a trial version of software drop box free for a month period was activated by me on 23.5.17. It was having terms and conditions such that it was necessary to fill up credit card details and to agree that after a month (If not renewed), it will get renewed automatically.
On 23.6.17 a transaction of 750$ trough my credit card np [protected] took place, though i am neither using the soft ware nor keen to renew the same.
My complaint on phone to customer care was already registered vide sr[protected]. Now attatching the cdf and credit card copy. Pl do needful for getting back the payment of 750$.
