Have been searching for an iphone*s. This guy posted an advertisement in the old portal , talked to him , came down on the price of **k from **k , asked me to pay *k after he ships the product , sent me the docket number of bluedart ( shipping number ) , sent me his details and his address , along with his aadhaar card , contacted him the next day , he didn't pick up , called him up again, after **th call he did pick up and told me to check with the local area blue dart office as the package might be there , went to the bluedart office and they told me the docket number is fake , have been trying to contact this seller nothing happened , tried to report his listing on olx nothing happened.
