I use paytm for recharge my mobile, dth, electric bill and for pay online on shopping sites. I am using it from last 1 yr when my friend suggest me about it, I never bought any thing from paytm.
So I will not comment on their shopping facilities and the problem I had heard.
I use paytm as walet foy paying and taking money from friend when unable to take physically. Their is no money problem in paytm, they even return money if there is any failure in recharge.
I never needed to call paytm customer service for complaining any problem, after I started using paytm, I not need to go outside or request anyone to recharge, even now I recharge my family, reative and friend by taking money. Thank you
