Coinbase is probably the most reputable company that deals with BitCoin. Right now they are going through massive user growth, so they may be slow to help you in the case that their software acts erroneously. However, to the best of my knowledge, many people who have vocally complained loudly about some issue with them have gotten their issues resolved, albeit a bit slower than they would have liked.
"Coinbase is probably the most reputable company that deals with Bitcoin"...according to who? Perhaps some would want us to believe that Coinbase is the only alternative out there, and perhaps there are employees of Coinbase who post here, but as I stated, these are facts. Sorry, but the fact is, Coinbase sucks.
And, Coinbase supporter, would you care to explain to me why all attempts at communication over the past three g*d* days are ignored? Yeah, that's so reputable...
Probably because they are dealing with the market frenzy which is going on right now. It sucks but you might want to contact your bank and let them know whats going on...
