There's also a higher chance for some coinbase employee to notice your problem and answer you there directly. I've noticed some people posting their problems with X on reddit and getting an unexpected answer from some company employee there, for example.
I'd have bigger questions if they found time to dick around on Reddit than devote their time to filling orders and submitting EFT's and processing. For the record, the money came out on Friday night, and the funds still aren't available. LOL. I figured the second ETH eclipsed my purchase price, they'd have made it available, but no. At this point, it's just costing them money.
