Actually I have savings account with HDFC, while acc opening, my occupation set to Self Employed. So I received pre-approved offer for Business Money-back CC. I took it that time with just 25K limit. I have other bank CC with 2L limit. Is there any way I can change it to Personal CC with Higher Limit? Or Should I cancel it and apply C2C for new personal card? I don't have Salary Slips though.
