Paytm.com is one of my favorite websites online. I always do my mobile recharges in this site only ( if I have to do it online) . Now they have included postpaid, electric bills, water bills, and many other. They have even started online market witb genuine like the flipkart. It gives good offers and extra coupons that can be used for getting discount on other products.
I like paytm the most because of the safety. It is a trusted website. If you ever occur any problem during transaction they even refund your money back. It offers a virtual wallet that can be used for various purposes online. Easy to use conversion of money from wallet to bank account can also be done.
I would recommend this website for online
