Why would I be the one to be frustrated if I was the one to make the mistake? I've sent the correct hash. Don't you understand?The service is what the service is.
Unless I'm missing something, the crux of the issue is that you sent the wrong hash, right? As in, if you'd sent the right one, then everything would be fine.
No doubt this would be more pleasant if QSC was staffed more appropriately for their sales volumes and were able to communicate more and be proactive. But face it, that would raise their costs and thus our prices.
TLDR: Send the correct hash.
