Hope you made sure he was banned from Nairaland. It's one reason why I have never tried any transaction on that platform.Last month, I was in need of $10 to add to my Paypal account. So I decided to ask on nairaland and a would-be seller got my contact after he claimed to have the funds. We negotiated on WhatsApp and agreed on 350/$ in order to execute the transaction. I credited him with 3500 naira after He sent his bank details. I informed them of the payment and after he confirmed it, he suddenly went offline and that was how he ran with the money. Luckily, for me, it wasn't more than $10. Be careful guys as you trade online. Many are not legit and desperately looking for who to hoodwinked.
There may be need for a market place there, controlled by the admins who will make sure both parties are satisfied before releasing funds.
