Unless you're on ATT you won't see the update for quite some time since OS updates have to go through the individual carriers first. That's why OS updates fire T mobile, Sprint, Verizon & ATT are never released at the same time. And since you're using an ATT model on Cricket, it's going to take even longer since they are usually the last in line behind the big 4 carriers.
The only way around this would be to use an ATT SIM card, take the update, then put your SIM back in the device. Otherwise, all you can really do at this point is wait.
But hey, at least you're device is working now, so that's good! [emoji41]
