Paytm is most commonly used during Notebandi.! It is very helpful app to be used in day to day life without any tension of cash.! As you have bank in you phone.
Customer Service- I must say that the customer service of paytm is not so good as it is important for this type of apps to have veru good customer care support as it is related to bank and finance.! I am personally Not satisfied with the customer sevice which they are providing!
Delivery Timeliness - I have placed few orders on Paytm and the experience has always been the same - bad. Today is 24/4/17 and I have placed order on 15/4/17 for a trimmer which I have not received till yet!
Apps and Websites- App and websites are easy to use. and can be use by everyone easily! Interface is very good and attractive. You can easily place order and check out. And have all order history along with bills etc.
Reliabilty- You can not fully reliable on Paytm as their are various buges and poor customer care support which is moset required in this type of apps.!
