Huh? Could you elaborate? Was that some transaction that got cancelled or something? I guess you wrote the support? It surely won't take this long to be executed normally! But any info on this would be appreciated!
Basically if you do research of Coinbase history you find out many sell/buy orders in the past were cancelled without any compenzation. Like you bought 1BTC when the price was 800 USD, but after few days your buy order was cancelled. The support tells you can do the transaction again, but unfortunatelly for you the price is now 850 USD.
So much about Coinbase.
