Spoke to them a couple of times over the last year to ask why my batches were taking so long to review. They would probably still be there pending had I not have chased them.
Once they've confirmed they'll process them, it's a couple of weeks until they're reviewed.
Regarding payments. Never had them not pay and usually payments are sent out on the 25th of the month. You might need to check your payout settings to see if you have an email address set up, or if you've completed the tax forms.
