Dining Plus — No service in apollo hospital to Dining plus card holder

Address:

Chennai, Tamil Nadu

This is Ramkumar from Chennai. I have Dining Plus card. (Card no is: 33 84993) I have got this card from Standard chartered bank with EMI option. They have told that one of the family members of this card holder can take full body check up in Appollo Hospital. Last week i enquired Appollo Hospital. But they told as the bond between Dining plus and Appollo finished and now they cannot give the service.
But still i am paying the EMI amount to Standard chartered bank for this card.
What i can do now?
Whether i need the free body check up in Appollo hospital or my money back.
