IDFC First Classic or Platinum Debit card from IDFC Savings account. which gives 2RP for each Rs.150, above Rs.20k Transactions you will get 10Rp for each Rs.150. and i got RP for CC bill payment from almost all the Platform(PayTm, MobiKwik, Cred, CHeq, but now I'm not sure about it, IDFC have updated their Tnc's which excluded CC bill payment for RP. SO someone else should confirm wether they have got it recently or not.
will check in two or three days and will confirm.
