This Undie by Sundas bank is not giving 3% gems for Jiomart txns via DC even if I set it as one of the top 3 brands. Gave only 0.5% which is the default for debit card. Customer care useless, Twitter useless, emails no use, even fake "RM" useless, escalation to Nodal officer useless. Only option left is RBI ombudsman.
