I was searching for mobile phone on OLX and came accross his ad. He contacted me on whatsapp for further details. I've been in conversation with him for 3 days related to the company and product details I want to buy. He asked me to pay tax amount in advance and rest amount on cash on delivery. On his suspicious behavior like offering me discounts and cheap price, I've contacted the best buy customer care support and asked them if this person is your company's sales executive. I then came to know he doesn't belong to the company and the products from the bestbuy don't ship to Pakistan. Meanwhile I got alert from OLX that this user has been blocked due to suspicious activities.Timely alert of OLX and bestbuy support saved me from this scam.

Whenever any person tries to contact you personally, kindly make sure if he actually belongs to the company he claims.
