Hello and welcome to the forum.
You're experiencing some of the most common worries new scorpion keepers have
. When you say you haven't seen it eat, have you noticed whether prey items have been disappearing? Or are they still wandering around the enclosure? If they're disappearing obviously your scorpion is eating, probably just at night time when it feels it is safest to be out to capture food. If it is not eating, 2 weeks is not a long time for a scorpion to go without food.
Burrowing is something this species will do a lot. They'll also more than likely spend the majority of their time in their burrows. Not leaving the burrow at all, and even sealing entrances to their burrows can be a sign that a scorpion is close to moulting. Have you noticed if your scorpion has a particularly fat, distended body? If it is about to moult then your scorpion will not be interested in food so you should stop offering it to avoid stressing and potentially causing it harm to your scorpion. Crickets in particular are notorious for munching on soft, defenceless freshly moulted scorpions.
This species is from Tanzania so I would advise increasing the temperature to the low to mid 80's (28c - 30c) during the daytime. I think 70f is too low for this species. A more natural temperature range will increase activity and appetite in your scorpion, and if it does turn out to be close to moulting it will also help ensure that it does so successfully.
