Consumer Redressal

Recently, i had received a call from a Standard Chartered Bank Credit Card representative adn was offered a Credit Card with commitment of a Minimum Credit Limit of Rs. 2 Lakhs. I already own an ICICI Credit Card with a limit of rs. 45k, with very good features. However, Rs.2 Lakhs limit was attractive and thus, i applied for the same. Now, when i received the card, the limit approved was just Rs.31,000, which is even lower than the limit on my existing Card. I have a decent salary and working with a reputed Bank. Then, when i approached the Service head of Standard Chartered, i was informed that there was no such commitment from our side and you will have to accept the limit approved. Also,it has been more than 15 days and i have not yet received the PIN for using the Credit Card. This is happened not only with me, but also with one of my colleague. Please Help!!!!!
