Still, it has been a long time since your transaction confirmed, they should really sort this out. Unfortunately, this is the danger of relying upon third parties for Bitcoin Wallets... you're effectively at their mercy
Log a ticket if you haven't... and/or add to the one you have pointing out that their original response was rubbish, and the transaction has over 1000 confirmations... the delay has NOTHING to do with Bitcoin network congestion... and EVERYTHING to do with CoinBase being useless
NOTE: You might want to word your support requests a bit nicer
Haha yeah I was nice in the emails but also tried to explain that they did something wrong. I started a new case last night and today I see they merged it with my old case. If they have the time to do that I would think they have the time to give me some sort of update.
