I have received two RBL cards in one month gap - World Safari & Indian Oil, however in both I have shared limit of only 50,000. I emailed them about limit enhancement showing my HDFC card offering 14 Lacs limit, HSBC offering 12 Lacs so 50k limit restricts my usage but they denied, rather mentioned apply for limit increase after 6 months! Anyone succeed in RBL limit enhancement?
