tax not charged to customer

Hello, My question is for Canada province of Quebec. The booking partner who collects the customers did not charge the taxes (accommodation tax, tpa and tvq) for 4 reservations. It seems that from January 1 to March 31, 2022, the system had a bug. Since we have to pay the taxes to the government, what can we do to be reimbursed by booking. Because it's not our fault.
