This is my oldest credit card(7 years now) and has never given me any problem except calling to customer service during 8am-10pm India time.
They were the first to offer refund of petrol charges. I once lost the card; called up customer service to get it blocked and get a new card. The whole process was so easy and efficient that I have never thought about cacelling this card even though I have used several other cards and got them cancelled due to their bank’s pathetic services.
The credit limit is set not too high and not too low which is good. The statements were always on time and correct and payment is always credited to your account.
However, since am a person who likes to make use of internet and computers as much as I can so I opted for e-statements. This is a grey area for bank. For purpose of security they provide a secure token which you use alongwith passowrd. This I feel is too much for a person who just needs to view his monthly statement! I have had some probs with their token but over all I am ver much statisfied with this card.
