Not being flippant.

If you and every other person who is always stuck in a queue really want to get their attention, unsub and stay unsubbed until they fix the problem. Right now, they have nothing to lose and everything to gain by waiting out the current situation rather than outbid and outpay for a limited resource.

I know it sucks to admit it, but that is the current situation and as long as everyone is still paying them, regardless of ability to access what you are paying for, then they would be silly to spend money to fix it.,
