Not sure if they're still chewing through backlog. I've ordered several times from QSC with zero issues aside from kinda slow shipping. Sent Tracy an order worth several hundred on 10/23 - have yet to hear anything back. When I say I haven't heard anything, I mean I've not even gotten the payment link or anything yet, so nobody's getting cheated, it's just very unlike QSC to take this long to respond. I have not followed up with a bunch of emails because I didn't want to make their backlog worse.
