Average quality products and privacy risk while shopping

Purchasing products from paytmmall due to the lucrative cashbacks offered by them
But their service is quite average
The products are directly handled by sellers
Also the risk of data leak is present, their are major fraud rackets going around paytmmall
Customer care is almost useless and not reachable over phone

Though the refunds are expedited, and return procedure is quite smooth with the payment safety provided by paytm
