Normally, the credit card companies are supposed to check against CIBIL list (i.e. a list which has creditworthyness info and the past track record of a customer) before issuing a card. Am surprised how you even got the second card, but considering how banks function, it is ok I guess. One thing is for sure: your credit history would be spoilt for good and you will never be able to raise loans. Not to mention, raids by collection gundas and possible litigation.
