Paytm is selling items more than MRP(Maximum retail price inclusive of all taxes), kindly check the details of items post receipt of it, as the response from Paytm reply would be not satisfactory and ill-logical and you’ll not get refund for the difference amount. May be Paytm is involve in fraud transactions.
Also kindly be careful while return if Paytm’s delivered item is defective, they deduct the amount without proper justification and refund the less amount than ordered value and don’t replace the items.
