I have been using the SBI Railway Credit Card for almost 2 and half years now and all the 27+ bills have been in my Inbox on time.
All the transactions shown are genuine and hope it stays that way. The customer care is nice actually . It connects/responds in time. The CC representatives are polite and helpful.
Payment option is awesome as I can pay it online using any bank. ( Payment shows up in my account in P+3 days ) Every details are available online. The only drawback is the Annual fees which I hate but apart from that I have had no troubles at all.
