I know this thread is a little outdated, but I did want to chime in and say thanks to those of you who've given testimonials to the trustworthiness of our service.  I operate WeSellCrypto and we are, in fact, a legitimate and trustworthy operation.

As for OP's experience, there's an extremely high chance his order was held for review for one of our various security/anti-fraud checks. Based on his reputation, it looks like this was a rightful hold.  Legitimate buyers can also face delays due to these checks, but we do always get things sorted. 

Unfortunately, this thread is the first result when someone Googles 'wesellcrypto' - I just hope most researchers scroll far enough down in the comments to see the positive testimonials.

@Bitcoinsupremo - where'd you see that I'm French?  Haha, you're right in that I don't try and hide my identity or anything like that, but just for the record I'm an American located in the US.

Thanks again for the positive responses.

Best,
Greg
