I wouldn't call it scam yet but I wouldn't call it O K neither when they don't resolve issues.
Bitcoin requires trust since transactions cannot be reversed and escrow services generally aren't used.
The only recourse against seller fraud is reputation.
This guy, Yankee/Charlie, stole money from me and did not acknowledge my issue. From this thread it's pretty obvious that he's stealing bitcoins from others. He's dishonest, so further appealing to him is just a waste of keystrokes.
The only thing one can do is to call him out in public for it so that he can't scam others.
I agree with you on one part:
In a Bitcoin economy where the buyer doesn't have to strip naked and proof he's trustworthy, the seller has to strip naked to get the trust needed to conduct business. That is much more efficient as you don't need a rating of all customers but only of the much fewer businesses. I like that. People vet the business and tell their results.
I don't agree that Charlie stole your money. I mean I don't like that he treated me and apparently you like a troll that's damaging his business rather than taking the issue serious within hours. That is not professional and yes, we both consider public communication of a services issue important of the vetting process which in turn Charlie seams to find unprofessional. He never was pro-active trying to settle my issues but in my case it was settled.
He repaid me the full amount I had sent towards his business.I see bitcoinwireless as a powerful tool to introduce friends to bitcoin and therefore it has a tremendous value that will not immediately nullified by some payment issues. I'm keeping an eye on this and as soon as it runs smooth, I will tell every Chilean with a prepaid phone about it but there's a long way to go unfortunately. The whole process would have to take no more than 5 minutes reliably and not charge some surprise fees.
