Paytm is my preferred website for any type of recharge. I am using paytm for more than a year now and I am very happy with it.
I use it for all type of recharges whether it is my mobile recharge, internet pack or topup voucher. I also use it for my dth recharge. Is it quick, fast, and reliable and the best part is the amount of cashback they offer on recharges anf also the discount they offer on various products is very good.
