Nice communication

Had a couple customers complain they didn't receive their in-store rebate. Cashiers have no idea what they are talking about. The employees working in the secton of said rebate sign have no idea what they are talking about. Managers don't know what they are talking about. My poor customer had to direct the sales clerk to the sign cause she didn't see one anywhere. Sales Clerk brings sign down to prove there is an advertised rebate we cashiers are suppose to do. Ok, need a manager cause my transaction has been complete. My present manager is busy ringing up customers during our mad rush. She calls for another manager. Sales Clerk speaks to manager before me. Apparently there were suppose to be coupons attached to the sign that the cashiers scan to give this in-store rebate, but the company didn't send the coupons, just the signs. And I said, We were suppose to know that. No note nor verbal command on what to do when a customer complains they didn't get their rebate. Nice communication. Apologized to customer and thanked her for her patience when manager was done giving her refund.
