Guys I am redacting this post as I have been asked by the bank for non disclosure as mentioned in TnCs else my account would be suspended. They had asked me to remove this as this violates the TnC related to not getting reward points for CC payments.
Use Cheq for Indus MC and IDFC, have got points for both. Although IDFC sometimes hold for big amounts from any merchant.
Only con is Rs 50k limit, if they suddenly change the MCC, it will be a huge loss.
Merchant name- cheq
After long delay got refund of my failed transaction I have decided not to use any third party app,will pay all cc bills through their respective app/website only. Mental peace is more important.
