PayTm is absolutely amazing website. I use this website for my recharges done may it be of mobile, DTH etc.
Everything is done hassle free and I need not to worry about anything. it is completely genuine website and so you can trust this website. everytime you do a recharge from it, you always get a cashback which is like cherry on the cake.
It gets added to you PayTm wallet which cam be used later on when you avail some another paytm service. I hope I was able to resolve your query. comment below fr any addiyinal query.
