My existing credit card is upgraded to a new card, during taking the consent partial information is provided and important details are kept hidden. This leads to a monetary loss in my reward points redemption. Currently, my existing Credit card is expired and Bank is yet to share the new Credit card with me. I have raised the complaint on Bank's helpdesk but even after many emails follow-ups, no resolution is provided. I have asked them that I want to continue with my existing card but I am yet to hear anything positive from them. There is no option in the Bank's helpline number to connect with the Customer Representative to discuss the concern, every option leads to an IVR system which is also no advance enough to provide the proper solution.

 On my existing Credit Card, one reward point is equal to one rupee while performing the cash redemption of the available rewards points.
 All the available rewards points are transferred to the new Credit Card which is yet to be delivered to me. Available rewards points in the upgraded Credit card are converted into a lesser amount while selecting the cash redemption option, for the rewards earned in the older Credit card where 1 reward point = 1 Rs.
 This is a monetary loss to me and this was kept hidden from me.
