Paytm is fraud online shopping site. On mall app they sell rpduct at cheap rates with cashback because they sells refurbished products and don’t tell us because they wanted to make money. Thats why they givea you cashback. If you will order anything from paytm then keep one thing in mind it is second hand product or used by anyone before. These people are fraud and sells fake product. They sometimes sells clones of real products like you will order$1000 iPhone 10 and they will send you iPhone 10 copy which onmy costs$100 thats why they will give you$5-10 cashback to make you to buy from their website
