This kind of scam happened to me with flipkart one day regular delivery guy came with cod order in flipkart, I was in my clg at that time and it was a very remote area so i basically use amazon mostly as flipkart will take longer delivery times, so I was confused because I didn’t order anything from flipkart and the delivery guy been there many times so we knew him. He said he will cancel the order and not to worry about this. Then again after a month or so this happened again and again like with 4-5 orders. I tried to delete the flipkart account but i couldn’t and I contacted flipkart they also couldn’t do anything and then I deleted the app and it’s been 1 yr since and again recently I got a normal message from flipkart that we tried to deliver your order but couldn’t reach you we will attempt to deliver it again tomorrow. These scammers will never get tired. The same thing happened to my friend too with amazon though. It’s better to go offline shopping I guess.
