They have developed a reputation for having poor, unresponsive consumer support. Try doing a twitter search for @coinbasesupport. At any given time, it's a horror show.

I personally discovered this after a time sensitive transaction took about 48 hours to complete because of a buggy deploy on their end. The only reason it didn't take longer was because I was able to track down a coinbase support employee on the bitcoin reddit.

Same. They accidentally repeated a buy I'd made 5 or so times-- and it took almost a month for the coins to appear in my account.

I ended up making a couple bucks off the deal. But I can't help but think how badly it could have gone.

Official Coinbase support is non existent in my experience. There are people on the Coinbase Reddit page https://www.reddit.com/r/CoinBase/ who seem to be able to move things along if you aren't getting any support from Coinbase.

So this seems to be a pattern. The link that I posted elsewhere in this thread and the occurrence there was precisely because of poor support. (Again, I'm not affiliated with that guy in any way)
