I am having a relatively substantial issue with Coinbase and their customer service has been nonexistent.  I have 3 outstanding sales where the proceeds from those sales didn't arrive in my bank acocunt as promised.  These sales amount to 123 83 33 btc where I am owed $24666.39 $16705.75 $6716.80 (update: The proceeds from the sale of 40 btc ($7960.64) on Oct 31st, scheduled to transfer Nov 5th did arrive in my bank today.) (update 2: Coinbase has returned the 50 btc from the missing sale and I was able to transfer that successfully out of Coinbase to my offline wallet.)

The biggest concern I have is the sale of 50 btc on October 29th that was scheduled to arrive in my bank account on Nov 1st that now shows in the transaction details of my account but does not show in my buy/sell history.  This can be seen in these screen captures.

Update: All transfers have been received.
