There's a negative balance on my Axis Bank credit card due to Grabdeals cashback. What I came to know from the community and also from the Axis customer care, the extra amount gets credited to the savings account within 7 days. But it has been 13 days in my case and still the amount has not been credited to my Axis savings account. Today, when I called the customer care, the executive said as this is Grabdeals cashback I cannot transfer it to my savings account. If and only if I pay excess from my side only then that can be credited to the savings account. Is this true?
