This is to complain that yesterday i ordered something by calling on your given no and my order was successfully placed. But today i got a call from a no saying that tge person is calling from shop cj and i have won a lucky draw of tata safari car. From the way he was talking i got to know that it's a fake call. But my concern is that how did he come to know my phone no and how did he came to know that yesterday i ordered something from you and got a message too. I immediately googled for this and found it fake from other reviews also.
Please make sure about the security of your customer's details. This is a serious matter since the person calls on your name. Someone could easily get trap in this. I also got this message
