If you recently cancelled the deduction should be stopped within 1-2 pay checks.
If you need to know the specific pay date when it will be stopped, contact BenefitHub Customer care at 1-866-664-4621 or email customercare@benefithub.com and they will have this researched with the billing team.
If any refund is due, the carrier will send it directly to you once they receive payment. Refunds could take 30-90 days.
