Want to pay OneCard by South Indian Bank bill 1L+ bill. ANY rewards possible via DC or UPI? Paytm used to allow South Indian Bank bill payment for months now it's giving some error - same as BOB - something wrong at operator's end. SBI Unipay or HDFC billpay have never even heard of South Indian Bank. And CRED is settling instantly but no rewards for any DC via CRED now? Or Cheq? or Mobikwik? Which gives RPs? Don't mention SBI DC as its reward rate is too low.
