Paytm is a service I would recommend especially when you are trying to meet your minimum spend on your credit cards to attain those bonus miles. You can use it to pay several utility bills, taxes owing, rent, tuition etc. etc.
And now, Paytm is running a promo where if you use my referral code PTM1792386, you will get $10 after you pay a bill of atleast $50. But act quickly as this offer expires on March 09, 2018.
(Note by using my referral link, Paytm may provide me a referral bonus too.)
