Re: what would I do, if I paid for coin and the seller refused to release it.
something triggered me to ask this question, As a new trader As I am, we know very well that binance is no longer in Nigeria any more. some weeks ago I paid for particular coin and the seller refused to release the coin to me, the next thing he do. He went Off line for about 3 hours before coming on line again,at the end of the day he released the coin to me after 3 hours. because binance security was so secured, if the person doesn't want to release the coin.you can quickly go to appeal and everything will be settled, after giving them the screenshot of your payment receipt.
I can't stop laughing mate, you made a mistake and released your coins to a vendor on binance exchange and the vendor didn't credit the money to you, and the vendor went offline 
so after 3 hours he came back online? So you reported him and he credited you the money. So what is the need to create this thread again? You have already sorted out the problem. However you have already reported the vendor with your proves and the vendor have no other choice than to pay you your money.
This thread would have been interesting if you didn't know what to do, we would have tell you how to deal with it, but you already know what to do.
I think I understand what you wanted to do, you would have created this thread as a means of alerting newbies like you never to release their coins if they hant received their payment from any vendor.
