For past one year we received call from them telling that we have done a sim card recharge with them and asked us persistently to disclose the credit card details. Beware never disclose any details even simple ones like DOB as they record it and some companies can get information about you to start a fake account to charge you. we changed our credit card so they could not deduct amount so started harassing at any time of the day by calling and scamming us. PLEASE READ REVIEWS OF ANY SITE ONLINE BEFORE DISCLOSING CRITICAL PERSONAL DETAILS!!
